On Saturday night Relixs Josh Baron celebrated his 30th birthday with a private party at Brooklyn, NY’s Paul Robeson Theater. In addition to a party mix curated by the newly minted Relix Editor-in-Chief himself, the evening boasted performances by The Rub’s DJ Eleven and the debut of Separated at Birth, featuring Marco Benevento, AGP keyboardist Rob Marscher and Dub Trio drummer Joe Tomino. Benevento and Marscher, who share an uncanny resemblance, first shared the stage when the Jazz Farmers opened for Addison Groove Project at Saratoga Springs, NYs Skidmore College in 2002 and have both known Tomino since his old band Actual Proof frequented the Boston club circuit. The evening’s setlist included instrumental versions of a number of songs, including Yo La Tengos The Room Got Heavy, The Shins Spilt Needles, Daft Punks Aerodynamic, Radioheads Weird Fishes, Wilcos On and On and On and Poor Places, Wax Stags Short Road and selections from King Tubby Meets Rockers Uptown, among others. During Split Needles, Benevento also included a bit The Duos own Play Pause Stop. I did cause it’s the same progression as Play Pause Stop, the keyboardist said. It’s just backwards. . . . weird. At one point the birthday boys father Bruce Baron even took the stage with the trio to deliver ‘the birthday song’ he often sings for students and faculty in Orange County where he serves as a principal.
