Music notes

At the Toys for Tots benefit Dec. 8 at Harry’s Watering Hole, Two-20-Two, Mama’s Trippin’ and The Vitriolics have promised to only do covers. … It should be a sing-along to remember, considering the crazy covers Eric & Friends have been playing at the Zephyr every Wednesday night. Mama’s Trippin’ guitarist Eric Stangeland runs this open mic. … I ran across KWMR-FM 90.9 on the way back from Thanksgiving vacation. Check it out if you like "music characterized by the emission of a succession of repetitive beats."
