"drums and percussion"
Roy Wooten, a.k.a. Futureman, is the percussionist in the Flecktones. He plays an instument called the SynthAxe drumitar, which he invented himself. It is held like a guitar (hence "axe" and "drumitar"), has many small buttons that each produce a different sound (hence "synth"). At Flecktones shows, he also plays real percussion, usually simultaneously with the drumitar.
