For his first show in two years, Si Schroeder brought a host of friends, from Tin Charm to 3epkano, to the lofty space of Dublin's Grand Social on Wednesday night. Bleeps and beats, glowering guitars and his sometimes whispered vocals filled the room like the voice of an old friend. There's an album in the works, with a few choice cuts unveiled here, but it was the more familiar tracks from 2006's Coping Mechanismsthat got the warmest welcome back.
