Lauryn Hill has been all about the surprise appearances recently. There was her show at the Catalyst in Santa Cruz a month or so ago where she apparently performed her stuff in a totally revised Afro-jazz-meets-rap style. And now reports come in describing her appearance at Rock the Bells this weekend, where she came on right before the rabidly adored Wu-Tang Clan. Hill played classics like “Doo Wop (That Thing),” “Lost Ones” and the Fugees’ “How Many Mics” but the reception she received was lukewarm at best. We personally would like her to ditch the duds, for a start. We get that she’s anti-industry but there’s never a good reason to combine sweatpants and sandals.
