Katy Perry, Halsey, MC Hammer and One Direction's Niall Horan were just a few of the celebrities dotting the red carpet at the Capitol Records Tower last night (Nov. 15) in honor of the record label's prolific 75 year history in the music industry.

Other acts on hand included 5 Seconds of Summer, Tori Kelly and Beck — and judging by the photos, the label-mates all got on swimmingly during the celebration, meant to honor 75 Years of Capitol Records, a Taschen photo retrospective commemorating the label's iconic history, from 1942 to today.

Roughly 1,000 guests — including legends like Neil Diamond and newcomers like Maggie Rogers alike — filled the outdoor space according to Billboard.

Check out photos from the party above, as well as a few photo booth moments below.
