Medicine's thundering, feedback-drenched monsoon of guitar chaos was an early '90s West Coast orphan of My Bloody Valentine. Sadly, that swirl has been replaced by this lobotomized antecedent. Eight years removed from their last album, "Mechanical Forces" reflects founder Brad Laner's more recent electronic excursions in Electric Company, with bubbling drums and clattering effects glazing over the diva vocals of Shannon Lee (yes, Bruce's daughter). While the melodies are still in place and appropriately enveloped in a wash of sound, the guitars take a backseat to the throb of synth-ridden techno funk. While intermittently entertaining, the songcraft of the old band is missing. Too often the album comes across as an asexual, less-compelling knockoff of Garbage, themselves an act whose creative well ran dry quickly.
