Charles Hamilton is back.

Yesterday, at the iHeart Media summit in Los Angeles, producer Ray Angry posted a photo to Instagram backstage with Hamilton and Rita Ora, and according to the caption, the two have collaborated on a song possibly called "NY Raining." Hamilton, who recently joined Instagram, posted a photo of him performing on stage with Ora—and some footage of him rehearsing on the piano. (No, this is not a new song, it's "Moonlight Sonata.")

A few weeks back, Thompson Studios tweeted a photo of Hamilton alongside The Invisible Men, the masterminds behind Iggy Azalea's hit, "Fancy." The trio previously worked with Ora on DJ Fresh's hit "Hot Right Now." Forums also picked up that multiple employees at Turn First Artists, the London-based music and branding company, who work with Ora, Azalea and The Invisible Men, listed Hamilton as an artist that will be big in 2015. Looks like Hamilton may make a comeback this year.
