Lumbard's music is Blues/Folk based but depending on where he's playing, you might find him covering a jazz standard, Robert Johnson, Lyle Lovett or doing a set of his own tunes.
Lumbard's finger-picking guitar style can be traced back to his high school years of listening to Hot Tuna, Doc Watson and all the Blues and Bluegrass albums he could get his hands on. His slide-playing has been influenced by Johnny Winter, Lowell George and Ry Cooder.
For slide, Lumbard uses a 1929 National, and for most of his regular guitar work he uses a 1935 Epiphone archtop. His song writing has been heavily influenced by the Texas songwriters and tends towards self-deprecating humor.
