The feud and fallout from the bitter breakup of power-trio-cum-meteor-shower Husker Du continues. First it was Grant Hart’s melancholy single, “2541,” named after the band’s studio address. Then came guitarist Bob Mould’s Workbook album and tour–searing, monstrous, and dense. With Hart (it was said) experimenting with heroin, and bassist Greg Norton (it was said) selling real estate, there (it was felt) it would end. But now Hart’s back (and cleaned up, he says), with an organ-laden, rocked-up return called Intolerance. There’s a Springsteen-meets-the-Pogues sing-along (“The Main”), a sicko instrumental (“Roller-Rink”), and a knowing portrait of a protesting-too-much loser (“All of My Senses”). But hovering over it all, again, is “Twenty-five Forty-one” (spelled out this time in recognition of a new arrangement), a painfully literal, almost too literal, breakup story, using an eviction as a metaphor for the disintegration of the band. If you can manage to get over the song’s killer hook, you think, cruelly, that this is only druggie self-pity. Get some perspective, you think–until the last line kicks in: “And it probably won’t be the last time I’ll have to be out by the first.” What a song. Hart played all the instruments on the record, and well, too; no word on who’ll be in his band, which he calls Nova Mob. Sunday, Lounge Ax, 2438 N. Lincoln; 525-6620.
