So much 5SOS, so little time!

5 Seconds of Summer finally dropped their long-awaited self-titled debut album in the U.S. this week, and Luke, Calum, Ashton and Michael have made their way around the press circuit, including performing in front of an enormous crowd yesterday thanks to Jimmy Kimmel.

The guys performed three of their hits in front of the die-hard crowd of fans, including 'She Looks So Perfect,' 'Amnesia,' and 'Beside You'. Needless to say, 5SOS totally rocked each performance, pouring all of their energy into the live show. And the fans were equally as passionate, singing out every lyric at the top of their lungs, especially when the band encouraged them to belt out the chorus. We love it.
