The Boston-bred electro pop band Freezepop is back to release their fourth record, Imaginary Friends, with beats that will leave your head bopping, your feet dancing and wanting more. After taking over the videogame world as a part of Guitar Hero, Guitar Hero II, and Rock Band, the trio is now ready to expand their fanbase with an album full of much sleeker and sophisticated sounds. The band will be performing at a record release show on Dec. 3 at the Mercury Lounge in Manhattan. Tickets are $12 and doors open at 10 p.m.
