Uncle Rock draws inspiration from Maurice Sendak, The Beatles, Woody Guthrie and Shel Silverstein, taking his acoustic "rock of all ages" for children to libraries, bookstores, schools, and theaters. Many of the catchy, rhythmically propulsive songs were born at his day job as a teacher's assistant for preschoolers, which he landed after four years as a stay-at-home dad. Uncle Rock delivers plenty of celebratory, goofy sing-a-longs, but the material doesn't shy away from shadowy elements of life, often showing how music can help one to face the dragon in the closet.
Uncle Rock's CDs of family music have won critical praise from The L.A. Times, The New York Times, and Cookie Magazine, to name a few. As of 2008, he has spent over a year in the Top 10 of Sirius Satellite Radio's Kids Stuff.
Before being dubbed "Uncle Rock" by his nephew, he went by his given name of Robert Burke Warren, playing bass in many rock-and-roll bands, including international garage rock titans The Fleshtones. He also spent a year portraying Buddy Holly in "Buddy: The Buddy Holly Story" in London's West End, and soon thereafter released an acclaimed debut CD, cited by The World Cafe's David Dye as "a gem of an album." This led to co-writing with Rosanne Cash on her Grammy-nominated CD Rules of Travel. Yet "Uncle Rock" is far and away the most fun he's ever had. The Los Angeles Times called Uncle Rock "Smart, inventive, music that really rocks." The Manhattan Parent Guide said "When it comes to music for the whole family, Uncle Rock knows how to please a crowd." Harp Magazine commented "Kids just wanna rock with Uncle Rock, whose colorful, engaging tales have made him a hit on the children's circuit." The New York Times called him "A star among the young." And The New York Post said "For kids' music with an edge, Uncle Rock is your go-to guy. Rock on."
