Though several miles outside of their home of Pittsburgh, the close friends admirably repped their hometown label Rostrum Records, which has played a massive role in guiding their successful careers. As co-headliners, the Miller-Khalifa tag team kept the largely teenaged crowd in high spirits with up-tempo, summer break-ready sets. Both of their performances crammed dizzying amounts of their young careers into hour-long sets, including radio singles, vintage mixtape tracks and other fan favorites.
With the sun setting, hip-hop wunderkind, Mac Miller, kicked off his set with his debut single, "Knock Knock" (2011), and charisma to spare. Though fans were still shuffling in from the parking lot to the beachside stage, the former Billboard cover star's fanbase was out in full force, marveling at his song-ending freestyles and impromptu singing. Front and center to the stage, two fans held up rivaling signs: "MAKE OUT WITH ME?" and "WANNA MAC?"
The set peaked towards its end when Mac payed homage to his former Pittsburgh workplace with the sentimental favorite "Frick Park Market." He also sampled tracks from his mixtape, "Macadelic," including his highest charting Hot 100 single to date, "Loud."
Rocking a white sleeveless tee, fedora, and the skinniest of skinny jeans, Wiz Khalifa took the stage shortly after and performed a few mixtape tracks as fans braced for his radio hits. Still, it was refreshing for the post-stardom Khalifa to pay homage to his stellar 2010 tape, "Kush & OJ," playing cuts like the Frou Frou -sampling, "In the Cut," and the Big Jerm-produced, "The Kid Frankie."
As the show wore on, Khalifa, now shirtless, sunk his teeth into more material from his third album, "Rolling Papers." With the stage lights now emitting a similar shade of green as the album's smoke-filled cover, Khalifa used his live band to his advantage. Although most of the crowd had heard "Black and Yellow" dozens of time before, the No. 1 single took on a new rockstar persona with the live drums and a throbbing bass line. Khalifa reminded the crowd, "We're not done," before his crew joined him on stage for a rendition of "O.N.I.F.C.," the title track of his forthcoming studio album.
Khalifa and Miller dipped further into the Pittsburgh rap scene when recuriting two of the night's opening acts: Taylor Gang's Chevy Woods and a fresh Rostrum signee, Boaz. Also playing earlier in the evening were Kendrick Lamar  and ScHoolboy Q  of the Los Angeles-based Black Hippy rap collective and the Philly alt-rap duo Chiddy Bang .
Seven dates remain on the 'Under the Influence of Music Tour' -- including today's stop in Camden, NJ's Susquehanna Bank Center -- before it wraps up Sept. 3 in St. Paul Minnesota.
