“The world’s greatest tuber” recorded their new album, the 60s psychedelic jam-athon Registration Round, at an empty House of Rock on a Sunday afternoon. The new CD is surprisingly listenable, even if you’re not into jamming for hours on end. Some tracks, like How Big Is It, conjure up images of ska, minus the horns and with an added cello and much funkier bass, while Goin’ Surfin, as you can imagine, wants you and all your friends to party on the beach till the break of day. Bassist and vocalist Greg Hirsch’s voice is deep, clean, and almost blues infused, while cellist Matthew Probst keeps things interesting with solos. Original members Thielen and drummer Matt Hankey round out the lineup, holding down the funk. The mix is also reminiscent of the band’s influences, which vary from Pink Floyd and Frank Zappa to Ween and the Raconteurs. “It’s only about two or three takes on all the tracks. It’s pretty garage-like, but clean,” says Thielen.
