Geologist

Brian "Geologist" Weitz is a member of Baltimore-based group Animal Collective. His main contributions to the group are in the form of sound manipulations and noises. This role has changed much during their career. Initially, he operated MiniDisc Players and created the noise of their harsh noise laden Danse Manatee and Hollinndagain. In their more recent albums his instruments of choice are samplers and effects processors. Over the years, his role as the "noise man" of the band have defined their albums, such as Strawberry Jam and Centipede Hz.

His only songwriting contribution to the band is a solo track found on the Keep EP called "Jailhouse." He has also created the soundtrack tho a short film named Man O War.
