Band SwapAs the Roman numeral indicates, this is the fourth year that a group of 35 local musicians have ditched their regular band mates and thrown their names in a hat to form seven bands. Those bands then have 24 hours to learn an assigned set of cover tunes.

Band Swap is co-organized by Jenn Bergen and Kathleen Dawn, and proceeds from the event will be donated to Carmichael Outreach. Last year, the event raised around $4400 and the goal is to raise even more this year.

Band Swap IV goes Saturday, Dec. 27 at the Exchange (2431 8th Ave.). Tickets are $15 advance and $20 door, and the show will start at 9 p.m.
