Shaggs fans, look alive: Dot Wiggin, one of the three sisters from the legendarily odd (perhaps unintentionally so) late-’60s–early-’70s New Hampshire pop trio, makes a rare live appearance, backed by a crew of young admirers. Expect to hear impressively faithful versions of warped Shaggs classics such as "My Pal Foot Foot," as well as tunes from a new solo LP, Ready! Get! Go!. Also on board is oddball-punk vet Jad Fair, of Half Japanese, performing with longtime collaborator Gilles Rieder.
