“We’re really happy to not be here tonight,” said Sun Speak guitarist Matt Gold during his duo’s Thursday-evening set at the Hungry Brain. The beloved Roscoe Village venue and bar, a longtime hub for the local jazz community, had closed in December 2014. It’s spent nearly a year dormant (and it’s not formally open yet—hence Gold’s joke), but a capacity crowd filled the room last night to help drummer Charles Rumback celebrate the release of his album In the New Year.
