Cosgrove's distinctive, creative flatpicking sound has been heard all over the US and Europe, as well as in Australia and Japan. A lot of this exposure
and travel is due to Mark’s association with Americana and roots music icon David Bromberg. In addition to touring with the Grammy nominated David
Bromberg Quintet And Big Band Mark had the great good fortune to be featured on the two most recent recordings of David’s, the latest of which, The
Blues, The Whole Blues, And Nothing But The Blues, was selected by The Downbeat Magazine’s Critics Poll as 2017 blues album of the year. Mark’s other
musical projects include recording and producing with his own band and others in the bluegrass and acoustic music realm. Not bad for someone who grew
up in a Manhattan apartment surrounded by classical music and whose original musical ambition was to become a drummer.
"My first instrument was guitar, but I started playing drums when I was 10 or 11. I learned from records and played in school bands," he says. "I still
love to play drums. I'm not a good drummer, and I haven’t touched the drums in years but I understand them. I think that helped me have a halfway decent
sense of time and feel for music. In any genre, I believe that feel and groove is as essential an ingredient as lyrics and melodies. It’s also just
one of the most satisfying moments in music when a singer or soloist appreciates that aspect of what I do. Sometimes it just takes a tiny little rhythmic
or chordal contribution to set something off in the music. Sometimes nothing at all is best!"
Cultural exposure in Mark's home was distinctly highbrow. His mother, Mary, was a successful costume designer for major Broadway musicals and the opera,
winning a Tony Award for her work in 1948. "My household was always full of friends of my parents who were involved in music and theater. None of my
immediate family members were musicians, and getting established as a musician myself, people assume there was a lot of bluegrass and acoustic music
in my household, but there really wasn't," he relates. "My parents and family loved classical music, and in my early days didn’t exactly get the music
I am so involved in and have made my life's work. Of course I suppose that was pretty understandable considering they were subjected to the sounds
of a fledgling flatpicker/drummer in his early days. It was a small apartment in Manhattan!"
After flirting with drums, Mark returned to guitar when he was about 15 as he met high school mates who were also into bluegrass and folk music, as well
as acoustic-flavored rock acts like CSN&Y. A ninth grade math teacher who played fiddle encouraged him, as well. But it wasn't until he heard the
glorious wail of Clarence White on the Byrds' "Untitled" album that the guitar really took hold of him. ""That knocked me out, when I took a look at
the layers of what Clarence White was doing," he explains. Around the same time, Mark heard Doc Watson and the famous "Will the Circle Be Unbroken"
album and made the connection between Doc and Clarence and the electric and acoustic guitar. "I was hooked by those guys and have been ever since,"
Mark says now.
Mark studiously pursued flatpicking, and went to work for guitar maker Augustine LoPrinzi, where he spent a summer sanding guitar bodies. The shop
had a Brazilian rosewood dreadnought on the wall that was considered a second. Despite their reluctance to sell anything considered less than their
best work, Mark persuaded his boss to let him buy the guitar for $100. "I used that guitar to win both Winfield and the Doc Watson championships. I
treasure it," he says.
In addition to playing acoustic, Mark also was studiously pursuing electric guitar, a lifetime endeavor which has had a profound impact on how he approaches
his flatpicking style. By the time he was 18, Mark had joined a local swing country band called Cross Country that covered everything from Western
Swing stylists like Commander Cody and his Lost Planet Airmen and Asleep at the Wheel to the New Orleans-based Dixie funk rock of Little Feat. "I was
and still am a huge Lowell George [Little Feat's founder] fan. I was knocked out by his phrasing," Mark explains. The band played professionally around
the Philadelphia area, giving him valuable exposure to the world of being a professional musician. Hungry for musical growth, he absorbed country-rock
licks and chicken pickin' style Telecaster leads from masters such as Ray Flacke, Albert Lee and James Burton, all the while continuing to soak up
influences from Clarence White's astounding breakthroughs on both acoustic and electric guitar. It all went into Mark's musical upbringing, creating
a daring and original style that wouldn't become fully realized until he started playing much more acoustic guitar in the mid-80s.
His first chance to do that came when he joined a Philly-based bluegrass band called the Lewis Brothers, which as Mark recalls, "didn't have a single
person named Lewis or a single brother in it." The band released two LPs and toured Europe, where he met future partner and excellent singer/songwriter
the late Liz Meyer. Working with a straight-up bluegrass band helped Mark hone his acoustic chops, but the demands of his day job as a carpenter kept
him from progressing as much as he wanted. Eventually, Mark and his then-wife bought a natural foods store selling everything from organic produce
to supplements. "That afforded me time to play more guitar and, in a physical way, I wasn't so exhausted and I had been doing contracting work," he
recalls. "I could concentrate really hard on my playing and did some major improving then."
Before long, he felt good enough to tackle the challenging guitar competition circuit. Making his first pilgrimage to Winfield in 1987, he entered
his very first guitar competition at the National Flatpicking Guitar Championships. "I didn't make the cut. I wasn’t ready for that level," he admits
freely. But he gained valuable experience and insight. "One thing that contributed to my not having any success that day was that I hadn't prepared.
I could improvise pretty well, and I had the outlines of my tunes down and thought I could just blow over the changes and be relaxed. I had no idea
of the quality of competition out there," he tells FGM. "I spent the next eight years pondering how to go about that and have more success."
With his new job, Mark could devote many more hours to developing and practicing contest arrangements. Diligently, he worked on his tunes and developed
his musicianship to a higher level. By 1994, he felt ready to take another crack at the big time, heading to Merlefest for the flatpicking contest
there. "I just wanted to get more experience; I had no concept that I might win," he says, adding that, "I got lucky that day." Buoyed by his success
in North Carolina, Mark returned to Winfield in 1994 and came home with a solid second-place finish, returning in 1995 and winning the top prize. That
year at Winfield,
Mark cracked the inner circle of top pickers, joining jams with two-time champ Gary Cook, the Kessingers and Steve Kaufman. "During my time off from
contests, I looked at Steve's real genius for arrangement and creating strong competition pieces," he says of three-time winner and contest legend
Mark has been a popular instructor at Steve Kaufman’s Acoustic Camps since the late 1990s and considers the camp to be the best in the world. “I’m
always excited to come back and be a part of the wonderful teaching and performing that goes on there. Steve and Donna have done a remarkable job.”
