Aggregation No. 1Quilt and Widowspeak with opener Doug Tuttle at 9 p.m Friday (doors are at 8 p.m.) at The Sinclair, 52 Church St., Harvard Square. Tickets are $15 for this 18-plus show.

There are so many bands playing in Cambridge and Somerville on any given weekend that there has to be something special about a bill to make it only a list of five entertainments citywide – but these bands have something special: a gentle, jangly pop sensibility that insinuates itself effortlessly into the listener’s head. Quilt (of Boston) and Widowspeak (of Brooklyn) especially have the uncanny ability to play original songs that make you feel you’ve always known them and always want to. They’re joined by opener Doug Tuttle (of New Hampshire), who joins in the dreamy, vaguely psychedelic vibe for what is guaranteed to be a sincerely groovy time.

Aggregation No. 4Dan Boulger comedy album release show at 7 p.m. Saturday at The Burren, 247 Elm St., Davis Square, Somerville. Tickets are $15 in advance or $18 at the door.

Dan Boulger was the youngest-ever winner of the Boston Comedy Festival in 2006, appeared on “The Late Late Show” and Comedy Central and somehow became a late bloomer anyway – but he’s finally released his first comedy album, “Not Ready For This.” After recording it live in Davis Square, he’s back for a victory lap with one of the most impressive lineups of fellow comics anyone could hope to see: Ken Reid, host of “TV Guidance Counselor”; the brainy Jono Zalay, whose debut album “Snake Oil!” was on the iTunes top 20 for weeks; Kenice Mobley, of the Women in Comedy Festival; and Lillian Devane, of Nerdist and the Eugene Mirman comedy festival; with host Steve Macone, of The Onion and “Last Comic Standing.” Information is here.
