Aly & AJ
Insomniatic
***
The second album from these Radio Disney faves takes a stab at maturity (or what passes for it in bubbly teen-pop) to intermittent success. Goofy lyrical metaphors abound in songs like “÷” and “Chemicals React,” but catchy melodies abound as well, at least throughout about half the album. No need to grow up too fast, girls; you’re clearly having plenty of fun being teens.
September 5, 8 p.m., $22-$25. House of Blues, 632-7600.
