Kid City and Fishery play in the middle of town Sunday, but they’re both extreme bands happiest on the fringes. This relatively mainstream opportunity to gig together at Hamilton’s transpired because “our families knew each other,” explains KC keyboardist Captain Kidd, who says Fishery bassist Green and he “used to play together at the beach, or be in day care together, or something.” Ah, memories. Not that either band is all grown up. Constant line-up changes and frequent reinvention of their respective sound (except the loudness part; both bands have never stopped questing for the ultimate high decibel levels) keep them young and brash. The Thursday show is a family benefit of sorts. A memorial service Monday night for Kidd’s aunt, who lived out of town and died last year, is bringing dozens of members of the extended family to town. So a concert was arranged. Also arranged: the promise of a hasty and no-excuses-required egress for curious oldsters who will quickly (and rightly) fear for their eardrums, not to mention their sanity.
Serious, doting grandmothers are expected. This will be one of those nights when the crowd is at least as interesting as the acts on that shallow Hamilton’s stage.

Different sort of scene at The Bullfinch Sunday as well: a bunch of theater kids from the college on the hill started a band to play in one of the shows there, and they booked a gig as an after-party for the closing night of the show. The band’s been dubbed Green Party Room, since they were founded in the school theater’s Green Room. Another “Room” band, Reading Room, was engaged to open the show. (Family Restroom must have been unavailable.)

Oh, the show? It’s called “No Babies, No Dirty Hands,” and it has its final performance Sunday afternoon. The band, cast and crew will bring their dirty hands and babyishness over to the Finch after they strike the set. Then the band will strike up a set, which includes such twinge-inducing titles as “Musical Planet,” “Magical Forest” and “Scenic Overlook.” Well, we’ll see—in rock as in theater, the acting is everything.
