Pop singer-songwriter Harry Styles appeared on "Saturday Night Live" on April 15. As the musical guest, he premiered new song "Ever Since New York."

Styles kick started his solo career earlier this month with the release of lead single "Sign of the Times." All eyes were on "SNL" last night to see him make his debut without One Direction. He played "Sign" in all the song's anthemic glory and it sounded more powerful in a live setting. Backed by a full band, Harry gave the performance his all and knocked it out of the park.

"Ever Since New York" is another song from Styles' upcoming self-titled album. Compared to "Sign," it's more subdued in sound, but still just as classic rock-influenced. With a half-buttoned shirt on, he strummed the guitar and crooned the new tune. "Oh, tell me something I don't already know," Harry soulfully sang with his backing band. In those few minutes, "SNL" felt like a blast from the past showcase from the '70s.

During Jimmy Fallon's episode, Styles also appeared during some of the skits. Most notably, he played a jittery Mick Jagger on the time travel edition of "Celebrity Family Feud." The Harry Styles album will be released on May 12.
