For the first time since the band's ill-fated "farewell concert" back in 2004, Phish returned to the festival setting on Friday night to headline Bonnaroo's main stage. And they killed it.

Performing for more than three hours, Phish slammed through their summer jam classics ('Down with Disease,' 'Stash,' 'Harry Hood'), showcased several new tunes ('Stealing Time from the Faulty Plan,' 'Alaska,' 'Kill Devil Falls') and ripped through covers like AC/DC's 'Highway to Hell' and the Beatles' 'A Day in the Life' as if they were written just for them. And just for the moment.

Indeed, it was a good moment and Phish fans get to experience it all again on Sunday night; that's when the band that inspired the original idea behind Bonnaroo is scheduled to close out this year's festival with a two-set grand finale. Better stock up on your glow sticks now, kids.
