The 58th annual GRAMMY Awards hit the Staples Center in Los Angeles on Monday, Feb. 15 for more than three-and-a-half hours of musical mayhem. Taylor Swift opened the show with a strong performance of "Out of the Woods"; from there, things quickly jumped from hip-hop (Best Rap Album, where Kendrick Lamar grabbed the night's first award) to country (a lovely duet from Carrie Underwood and Sam Hunt).

The first non-genre prize, Song of the Year, went to Ed Sheeran (who won his first GRAMMY shortly pre-telecast) and co-writer Amy Wadge for "Thinking Out Loud" (Swift, also nominated, was psyched out of her mind). Stevie Wonder did the honors, flipping open the envelope and teasing the crowd that only a Braille-speaker would be able to read it.

Taking home the rest of the biggies were T-Swift's 1989 for Album of the Year, Mark Ronson and Bruno Mars' "Uptown Funk" for Record of the Year and Meghan Trainor, who tearfully gave the most emotional speech of the night while accepting her Best New Artist award.

Live collaborations characterized much of the night; in addition to Carrie Underwood and Sam Hunt's, you had: Justin Bieber, Diplo and Skrillex wilding out with a bunch of live instrumentation; Demi Lovato, Tyrese, John Legend, Meghan Trainor and Luke Bryan teaming up to honor Lionel Richie (who himself popped up for a bit); Pentatonix joining Stevie Wonder for some a cappella fun; Jackson Browne and The Eagles remembering the recently deceased Glenn Frey; Tori Kelly and James strumming along with each other; Chris Stapleton, Gary Clark Jr. and Bonnie Raitt paying homage to B.B. King; Alice Cooper, Johnny Depp and Aerosmith's Joe Perry reminding us they're in a supergroup called The Hollywood Vampires; and Pitbull, Travis Barker and Robin Thicke festively closing out the night with some help from actress Sofía Vergara.

The cast of Broadway's Hamilton made history by broadcasting live from Richard Rodgers Theatre in New York City—and by getting the entire GRAMMYs audience to actually unanimously enjoy something. The seemingly impossible-to-follow performance was met by an equally theatrical and grand appearance by Kendrick Lamar. Other onstage highlights included AdeleAlabama Shakes and, of course, Lady Gaga's pitch-perfect David Bowie medleyRihanna canceled her previously publicized performance.
