No, not your Aunt Ediths raspberry preserves. KUBE 93.3s annual Summer Jam is less homey but plenty tart. This years lineup of internationally-acclaimed artists includes Ludacris, Nas, Bone Thugs-n-Harmony, Baby Boy, Mike Jones, T-Pain, and the Shop Boyz. Summer Jam V.I.P. Ludacris (along with T.I. and E-40) was a highlight of last years festival, and hes heroically recommitted for 2007. Mellifluous veteran rappers Bone Thugs-n-Harmony have made something of a post-Bizzy Bone comeback with this years Strength & Loyalty. Butdespite fans deepest wishesthey probably wont be able to smuggle Mariah Carey past airport security to perform their duet Lil L.O.V.E. live. A small sampling of hip-hops latest graduating class is attending, too. Hurricane Katrina survivor Baby Boy da Prince is evidence of New Orleans enduring music scene, and might lend some solemnity to the occasion. Newcomers T-Pain and Mike Jones, on the other hand, appear to just barely manage to drag themselves out of the club to join the other platinum-selling artists.
