Dan Donegan is an American musician, who currently serves as the lead guitarist for heavy metal band Disturbed. Donegan began playing guitar as a teenager and eventually formed a band called Vandal, which was an 1980s-style hair band. Donegan is a self-taught guitarist. He uses one handed and two handed tapping in many of his solos, with pull-offs, legatos and hammer-ons, also sometimes using the "flick off" technique, as used in the solo for the song "Indestructible", and in others as well. His heavy riffs and sweep picking are seen in many music videos.
