The only thing missing from Unsane’s 2005 comeback, Blood Run, was, ironically, a bloody cover star to compete with 1991′s Unsane and 1993′s Total Destruction. The rest of it was classic Unsane — Chris Spencer’s pulverizing chords and tortured vocals over Vinnie Signorelli’s thundering drums. But 2006′s Visqueen found them decamped from metal stalwarts Relapse to the more experimental (but no less heavy) Ipecac. And, with a dead body in place but looking almost artful, it had to be questioned whether the band was getting a little too refined for the tastes of its fans. But not for Unsane the type of experimentation that would have had longtime AmRep fans scratching their heads; Visqueen is an album on the ’90s model. The material isn’t as powerful as Blood Run, but the trio stretches out its sound in spots, including the 11-minute closer, “East Broadway.” – John Bush
