Kosek is one of the most recorded fiddlers in America today, having been the feature soloist on hundreds of albums, soundtracks, and jingles. He can
be heard on recordings by James Taylor, Jerry Garcia, David Byrne, Chaka Kahn, Willie Nelson, and John Denver. He has been a frequent guest player
with the Late Night Band on Late Night with David Letterman. Kenny's distinctive roots music-inspired compositions have been used in the documentaries
The Way West, The Donner Party, Harlan County, U.S.A., The High Lonesome Sound, and the Broadway musicals Big River and Foxfire, NBC's Another World,
CBS's Guiding Light, and Fox's Kirby Kids. His most recent CD, Angelwood on Rounder Records was called "a lovely piece of work with a strong hint of
the spiritual" (David Hinkley, Daily News); "an album that will surprise and delight fans of fiddle music in all its many forms" (Bluegrass Unlimited);
and "Kosek's signature sound—a swinging, smooth, and creamy hot rise that is as hard as it rocks, has exponentially enhanced every project he's
lent it to" (Village Voice).
