Lil Wayne and Drake square off at the Susq

Master and student. Mentor and pupil. Young Money founder and MC Lil Wayne, 31, and Canadian actor/singer/rapper Drake, 27, have long had such a relationship. But Drake has had a hot time on the charts since 2010, so he's certainly caught up, maybe even surpassed Weezy.

That's the set-up, anyway. And, to play along, their Street Fighter video-game-themed Drake vs. Lil Wayne tour, which sold out Camden's Susquehanna Bank Center on Thursday, was meant to settle the score for world supremacy - at least for that night. An app made for this show let the audience vote on which man outdid the other.

The two artists alternated three-song solo mini-sets, with energy closer to a battle of DJs than to one of rhymers. A shirtless Wayne started with the scowling "John" and "We Be Steady Mobbin," followed by Drake, resplendent in a white "Free Meek Mill" T-shirt, nasally rapping through the atmospheric soul of "Draft Day" and the near-pugilistic "The Language."

Beyond their rap trade-offs, the two verbally jousted as if doing promo for a coming boxing match. When Wayne spat, "I been doing this since little boy was in a wheelchair," he was referring to Drake's character of Jimmy Brooks on the Canadian TV show Degrassi: The Next Generation. Drake then brought out a tiny T-shirt for his shirtless pal. They baited each other - fun, though they've done this on cue throughout the tour. While Wayne chided young Drake for not being able to "go back" to riveting early smashes like "Mr. Carter," and "Go DJ" ("he has hits, I have classics," stated Wayne), Drake stressed his newer energy, as in the hauntingly repetitive "Versace."

One other thing: Drake could croon. On spare ballads such as "Find Your Love," Drake soared atop the crowd on a flying mini-stage. Not to be outdone, Wayne got all acoustic guitar and Wyclef Jean on the audience with a swishy, sweet "How to Love." But Drake was certainly the more effective romancer.

For the finale, they stood together on stage performing clips of their faves. Drake won that face-off with the anthemic "Started From the Bottom," and he also won on the app-based audience challenge. The closing number was a duet on the harsh, slow "HYFR."
