Sat. Oct. 28

The Middle East has its share of rock bands impersonating other rock bands on Tuesday, but T.T. the Bears, just around the corner, beats the Middle (timing-wise anyway) with ... the same thing! Just different real bands and fake bands. This Halloween could make for one heck of a time-trip for the Cambridge clubgoer. T.T.'s is calling this Saturday's show the "Hall-and-Oates-Oween Party," which means the headliners are the Rudds as Hall and Oates (they'll play a set of originals, too); the World's Greatest Sinners will fake it as Sly & the Family Stone - they'll certainly be better than Sly was during that weird Grammy segment - and Silver Lining as The Who. The merriment starts at 9 p.m. and costs $9.
