From the first song, the stately, shimmering “Gold,” the opening track of Robert Pollard’s sprawling double album From a Compound Eye (Merge), notice was served at the Paradise last Friday that his first solo tour would be a different beast from the raucous, shambling piss-ups that marked Guided by Voices gigs of old. Sure, there were plenty of the buzzing fuzzpop gems, psych-garage-punk nuggets, and shoulda-been smashes that make up the vast, almost unquantifiable idea dump of Pollard’s infamously prolix discography. But his new backing band — guitarist/keyboardist Tommy Keene, guitarist Dave Phillips, bassist Jason Narducy, and drummer Jon Wurster — brought a more workmanlike professionalism to the material, keeping the songs tight and giving them more-expressive tonal dynamics.
