This weekend: Ian McLagan at Martyr's and a look back at Chicago's alt-era music scene with "Rewind"

A Zelig-like character who was one of the most respected and versatile musicians on the British rock scene of the ’60s and ’70s, Ian “Mac” McLagan may be best known for his role in the Faces, and he recently had a reunion of sorts in the U.K. with former bandmates Ronnie Wood and Kenney Jones and guest Bill Wyman on bass. Those names aren’t likely to appear with him onstage Friday, Nov. 20, at Martyr’s, 3855 N. Lincoln, but you never know who will join him, or how far and wide his set list will range. The show starts at 7 p.m., and tickets are $15; call (773) 404-9494 or visit www.martyrslive.com.

One of the most promising groups on the Chicago rock scene of the early ’90s, though it never achieved the success of peers such as Veruca Salt, Tart was a trio led by Joy Gregory and Laura Eason, both of whom also performed with the Lookingglass Theatre. Now, Eason has written a play called “Rewind” inspired by her time in the band and the rock scene of that era, including the sad death of Jim Ellison of Material Issue. Produced by the Side Project Theatre Company, 1439 W. Jarvis, it opens at 8 p.m. Friday, Nov. 20 (tickets are $18) and runs through Dec. 20 with several showings a week.
