Plenty of nifty shows this weekend. Murder by Death (click the video for a taste) and O’Death play a lively show at the Grog – a roots-rocky affair that has nothing to do with the kind of metallic noise you normally think of with “death”-related bands. If you dig show tunes, Bernadette Peters is at Playhouse Square. And if you’re looking for something different, check out the largely unclassifiable Why?, who record for the always-offbeat Anticon label. – D.X. Ferris
