As of this writing, it’s a balmy six degrees outside, and the rest of the week’s temperatures don’t look too welcoming either. Use this week’s roundup of free and cheap music in Brooklyn to help keep your ears warm. You can start by heating them frigid hands by the funky fires of The Jam Stampede at the Brooklyn Bowl on Tuesday, and follow up with free shows by the buzzy bands Ava Luna and ARMS later in the week. As always, all the shows below are just $5 or less.
Monday, Jan. 24
