Perhaps the most famous ribs in Boston last year were the ones Jacoby Ellsbury fractured, ribs that forced the Red Sox outfielder to sit out most of the 2010 season. Now that the Fenway heartthrob is all healed up, 2011’s ribs to watch are of the rock-n-roll variety. One of the louder members of our Class of 2011, RIBS the band are poised for a breakthrough. The anthemic “Please Don’t Go” — one-half of the Locrian Singles, which gets the release treatment tomorrow (January 28) at the Ryan’s Smashing Life 4-year anniversary party at TT The Bear’s — is an almost-industrial gear-grinding stomp-along rock hammer, its brute force skillfully offset by the falsetto of vocalist Keith Freund. A follow-up EP to last year’s sterling British Brains is almost finished, and a tour along the east coast is planned for April. But for now, RIBS are Boston’s treasure, so check them out in Cambridge tomorrow night and grab the mp3 below.
