Fans of more grown-up R&B — the kind that usually hinges on actual music and real soul as opposed to synthesized computer beats — are in for a treat Saturday at Toyota Center when the Budweiser Superfest returns. In its original incarnation, Superfest was an annual urban-music staple from the late '70s until the very early '90s; its renewed form, in an applause-worthy move, still focuses on quality R&B instead of the latest trends. Among the lineup highlights is Raheem DeVaughn, whose buttery voice graced numerous hooks on last year's excellent but sadly somewhat slept-on Ghostface Killah solo album, but the other young performers also boast timeless voices. Seniority goes to Anthony Hamilton, who raised eyebrows and melted hearts on 1996 debut XTC, but Jaheim has been around for more than a decade and is also approaching classic status. Many may know him from his appearances on Jadakiss tracks, but he shines solo, too, and his latest album, Another Round, has already peaked in the Top 5 on several charts. Kem, meanwhile, is jazzier than his tourmates, so expect a live band with serious chops backing him.
