Bob Mould first grabbed attention in the 1980s, making a notable noise with Husker Du, the punkish Minnesota power trio for whom he was the voice, the guitar and writer of most of the songs. It couldn’t last and it didn’t. He spun off solo, then made a couple of excellent albums as a band called Sugar before going solo again. Patch the Sky (Merge Records) is Mould’s new album and quite a return to form, with a dozen fierce pop songs surging with his trademark sweet tunes and stun guitars – walls of them. He doesn’t really do ballads, though last track Monument does run a little slower that all the hooky tumult that precedes it.
