This is the first comeback single from the Black Eyed Peas called Awesome. It premiered during David Guettas Coachella performance as a remix and later the studio version premiered as the theme song for 2015 NBA Playoffs sounding very different. This song seems to be performed only by the original BEP trio Will.i.am, Apl.de.ap and Taboo with Fergie missing.

They really seem to be excited to be back.
