Jatnna Nunez for Fuse

Last night, Ralph Lauren celebrated the two most famous faces of its fall/holiday Denim & Supply line with an intimate concert at New York's iHeartRadio Theater. Cody Simpson and Tinashe headlined the party that spotlighted their two distinct performance styles and, at the end, fused them together for a never-before-performed song.

Cody kicked off the night with a showcase that highlighted the folky, rock-driven route he explored on his latest album Free, his first independent release. Walking out in a gray T-shirt and black jeans, the 18-year-old moved through Free tracks like "Thotful," "Driftwood," "New Problems" and the LP's title track. 

Simpson dedicated a significant portion of the performance spotlight his guitar skills, venturing on a few electric guitar solos and leading bluesy jam sessions with his three-man backing band that had the crowd's heads bopping and eliciting loads of audience cheers.

But if Cody was all about the drawn-out jam sessions for his four tunes, Tinashe was all about the cram session. The R&B-pop chanteuse moved through 11 songs, running out to her hit "All Hands on Deck" in a leather jacket and green jumper, before quickly tossing the jacket to reveal a practical black tank top that would come in handy for all the intense choreography she showcased. 

The set focused mostly on songs from T's debut Aquarius album, including standout moments like "If You" (which moved from a ballad-esque performance to a tropical, dance remix version), "How Many Times" (that spotlighted how she can nail songbird-like high notes) and "Bated Breath" (which focused on the low, alto notes she can also nail just as well).

Tinashe also performed snippets of her biggest collaborations including a dance-heavy version of her Calvin Harris collab "Dollar Signs," a sexed-up rendition of her "Jealous" remix and an powerful performance of her new song "Party Favors," which is off her upcoming Joyride LP.

The night ended with Tinashe and Cody coming onstage to perform their cover of Charles Wright & the Watts 103rd Street Rhythm Band's "Express Yourself." While there was some technical delays to get Cody's guitar set up ("We've never done this before so bear with us," Tinashe told the crowd who was more than happy to wait), the two rocked the live debut, perfectly capping of a night that combined different people from the music and fashion world into one memorable concert.
