With SXSW 2015 in full swing already, we’ve already been surprised by a number of awesome guest appearances. Check out the mayhem from this Saturday.

Surprises by T.I., Lil Wayne, Questlove, and Mark Ronson on multiple stages throughout Austin created a ton of hype on Twitter yesterday. While footage and photos are limited, The Belmont, RSVPster, SayItAintSxSW, and the one and only Rand Paul all managed to tweet out information about the performances.

T.I. dropped his latest album, Paperwork, in October 2014. The album climbed to #2 on the US Billboard 200 and #1 on US Billboard Top R&B/Hip-Hop Albums.

FYI: The Lil Wayne show is private & invite-only. #SXSW

The last time Lil Wayne was in Austin was back in September at Austin360 for the “Drake vs. Lil Wayne” tour. In addition to this surprise appearance, he will also be performing at the Coliseum on March 20, but the concert will be entirely separate from SXSW.

Questlove was featured in the new 808 documentary by You Know Films and Atlantic Films. In addition to his surprise at SXSW, he also made a surprise guest appearance on the NBC comedy Parks and Recreation as Levondrius, Retta’s long-lost brother.

Mark Ronson’s latest album, Uptown Special, is a smooth, funky project that features the massively popular single “Uptown Funk” featuring Bruno Mars. He also recently produced the beat for “Baby Blue” featuring Action Bronson and Chance the Rapper.
