Dinowalrus is an American band from Brooklyn, New York.[1] The group was formed in 2007 by vocalist/guitarist Pete Feigenbaum and synthesizer/bass/clarinet/guitar player Kyle Warren. After working on a batch of loose krautrock-inspired improv pieces with a rotating cast of drummers including Andy Bond (aka Oliver Duncan, who would later join Friends) and Etienne DuGuay (who would later join Real Estate (band)), Feigenbaum and Warren began settled down with 18-year-old Belgian drummer Josh Da Costa and began writing and recording the album that would become % (pronounced "percent") throughout 2008, while playing gigs regularly around New York with the likes of Titus Andronicus, Parts & Labor, Aa (Big A Little a), A Place to Bury Strangers, DD/MM/YYYY and Grooms.
