In an ideal world, R&B crooners Boyz II Men would have stuck to their new jack swing roots. But 23 years since their debut, they’re lobbing just about every genre against the wall to see what sticks – for the most part, it’s just confusing. As a body of work, Collide snaps from sounding like Chris Brown’s slick hybrid of bass-heavy hip-hop and R&B to Evanescence’s weepy piano balladry to Jack Johnson’s inane acoustic guitar beach-pop. It’s enough to give you whiplash. Or, in the case of Already Gone’s dubstep breakdown and odd staccato vocal chorus, it might just result in a dull headache. Regardless, Nate Morris, Shawn Stockman and Wanya Morris (no relation) still layer a gorgeous harmony – even as a three-piece minus Michael McCary. Atop jazzy chords on Believe Us, and amid Don’t Stop’s funk drive, their voices retain the silky quality that first catapulted the group to fame in the 90s, and no amount of disconcerting Auto-Tune or unfocused genre-hopping can taint that.
