Kimya Dawson and Friends, ‘Alphabutt’: Aidin Vaziri | Kimya Dawson, a member of the anti-folk duo Moldy Peaches who has a thing for wearing bunny suits onstage, became an unlikely pop contender thanks to her contributions to the “Juno” soundtrack. On her latest solo release, “Alphabutt,” she lends her slight voice and even slighter stream-of-consciousness lyrics to a set of 15 barely produced songs intended for children. With contributions from friends and her 2-year-old daughter, Panda, the whole thing sounds like an off-the-cuff soundtrack to a demented birthday party. Most of the tunes make a mockery not only of music but also of kids. There’s a great punk sensibility at work, but it’s doubtful that even Dawson listened twice to songs such as the grittily psychedelic “Wiggle My Tooth.” At the same time, the frizzy-haired singer has never sounded so elated, and it’s hard to deny her so much joy.
