Multi-hyphenate Kristin Hersh likes to keep busy. She founded alt-rock band Throwing Muses with her stepsister Tanya Donelly (the Breeders, Belly) when both were in high school, and has performed with the band since its 2003 reformation. She also began a mostly acoustic solo career in 1994 with eight releases to date, most recently Crooked. Plus, she founded punk trio 50 Foot Wave in 2003. But that’s not all. Hersh is also the author of a children’s book (Toby Snax) and a memoir (Rat Girl), and she added “nonprofit founder” to her resume in 2008 with CASH Music. Luckily for fans, her creative wellspring seems nowhere near close to running dry. Triple Door, 216 Union St., 838-4333, thetripledoor.net. 7:30 p.m. $15 adv./$18 DOS. All ages.Anacortes-based singer Karl Blau’s latest release, Maherican Dream, came together after an “I’ll scratch your back if you scratch mine” agreement with Olympia folk-pop band LAKE, in which Blau agreed to produce a LAKE record (Circular Doorway) if the quartet backed him on his. In Olympia, Blau and LAKE improvised, using a variety of sounds to create an eclectic mix of instrumental tracks. Blau then wrote lyrics for each (except “7 Sisters,” “Big Kalimba Blues,” and “When the Trees Take to Dancing”) based on what each track made him feel. Some tunes lean toward folk while others head down an ambient route, perfectly combining Blau’s and LAKE’s go-to sounds. With Little Wings, With Child.
