Watch: American Authors at Red Bull Sound Space

Live stream starts at 3 p.m. PT/6 p.m. ET, followed by a 24-hour replay.

American Authors have only an EP and two singles under their belts, but it helps that the second of those singles, the ubiquitous 'Best Day Of My Life,' is a relentlessly upbeat song that’s been featured on a glut of ads and trailers) and the EP track 'Hit It' is featured the FIFA 14 video game.

Now, with their debut album, 'Oh, What A Life,' just released and a headline tour around North America, the Def Jam artists are staking an early claim as your sound of the summer.

After forming as The Blue Pages at the Berklee College of Music in Boston, vocalist/guitarist Zac Barnett, guitarist and sometime banjo man James Adam Shelley, bassist Dave Rublin and drummer Matt Sanchez soon changed their moniker to American Authors, moved en masse to Brooklyn and began knocking out the pop-punk sound that’s been garnering them instant attention.

Watch them perform an intimate set live in the Red Bull Sound Space at KROQ today at 3 p.m. PT/6 p.m. ET. The entire set will replay on a loop for 24 hours afterwards.
