Kid Cudi's second Coachella set bought a surprise. Kanye West came through to help him rock the crowd.

The duo performed a few of their most recent collaborations, including "Father Stretch My Hands, Pt. 1," Kid See Ghosts' "Reborn," and Ye's "Ghost Town." 070 Shake also appeared to help out with the latter. Watch the clips below. Kid Cudi and Kanye West also previously linked up to perform at last November's Camp Flog Gnaw.

Kanye is in town to deliver an edition of his popular "Sunday Service" series for Easter. Coachella's organizers originally planned to have 'Ye headline the festival, but talks fell through once they couldn't follow his extensive production demands. Kanye previously headlines Coachella in 2011.
