Members of Groove, the University of Michigan percussion ensemble that creates music largely out of found-object instruments, offered a free lunchtime performance on the U-M Diag today.

As described on its website, Groove uses "traditional and non-traditional instruments to blend comedy, energy, personality and choreography into performances on stage and on the street. From propane tank hang drums to tubular xylophones, the instruments are the most creative in town, constructed out of construction equipment, everyday knick knacks, and anything else you could think of."

The appearance on the Diag promoted the group's upcoming concert at the Michigan Theater. Called "Scrap Metal Symphony," the concert is set for 7:30 p.m. Friday, March 23 at the Michigan. Tickets are $8 adults/$5 students; for more information, see the Groove website.
