Back in its heyday in the ’70s and ’80s, Aerosmith was one of the fiercest rock acts on the circuit. Albums such as Toys in the Attic and Done with Mirrors are classics. Draw the Line, which bills itself as “the only Aerosmith-endorsed tribute show,” tries to recapture that magic. Lead singer Neil Byrnes has even won Steven Tyler look-alike contests. The group plays tonight at Rockin’ on the River. Velvet Shake starts things off at 5 p.m. Admission is free. (Niesel)
