Thanks to a harmonic convergence of new fatherhood, abused eardrums, and proximity to the Big 4-0, a certain generation of hard rock musicians is laying down its electric guitars and penning pretty ballads. Or maybe it's just a coincidence that both Dave Grohl and Frank Black are nurturing their inner troubadours. Either way, it makes for a lovely double bill.
During his opening set at the Wang Center on Tuesday, Black (who moonlights as frontman for the Pixies) plumbed his eclectic solo catalog and transformed choice band cuts -- ``Wave of Mutilation" and ``Cactus " -- into intense, stripped-down affairs. Despite the gentler decibels there's nothing comforting about Black's music, which these days veers toward American Gothic in sound and spirit. When Black hollers ``Hey!" we still bolt.
