Charles Hamilton is making music again. At the iHeart Media Summit yesterday (Jan. 22)—the same place Kanye West played his collab record with Rihanna—producer Ray Angry posted a photo on Instagram of Hamilton and Rita Ora. Based on Angry's caption, it looks like Hamilton and Ora have collaborated on a track, possibly called "NY Raining." The New York MC, who made XXL Freshman Class back in '09, posted a picture with him and Ora performing on stage. The Instagram newbie also posted a video of him playing Beethoven's "Moonlight Sonatta" on the keys. Watch the video below.

Another thing to note is the picture of Hamilton, Ora and The Invisible Men that was tweeted out by Thompson Studios. The Invisible Men co-produced and co-composed Iggy Azalea's "Fancy." To make matters even more interesting members of Turn First Records—a London-based music and branding company who work with Rita Ora—name Charles Hamilton as an artist to look for in 2015.

C.H. has also been considerably more active on Twitter and recently sent out his official Facebook page. Fans have been tweeting him constantly, elated to see that the "Brooklyn Girls" rapper is back. The last time Hamilton released music was in April 2014 with Spud Mak called hip hop.
