Boston band (T-T)b headlines tonight’s live music at Deep Cuts, celebrating today’s release of their new album “Beautiful Extension Cord.” (T-T)b describes themselves as “deep-fried bitpunk for short attention spans.” The trio — Joey Dussault, Nick Dussault and Jake Cardinal — writes music about feelings, TV shows and extraterrestrial life, and they’ve quickly developed a cult following in the chiptune scene. Also performing: Really Great and Puppy Problems. Tickets are $12 in advance, $15 show day through Dice.
