Sufjan Stevens has teamed up with two Anticon artists, Son Lux and the rapper Serengeti for a new project called s / s / s. They'll release the four track Beak & Claw EP on March 20 via Anticon.

The six-minute track "Museum Day" features Sufjan singing Auto-Tuned lines alongside rap verses from Serengeti. The EP features vocal contributions from Shara Worden of My Brightest Diamond on "If This Is Real", while Doseone from Subtle and Themselves appears on the closer, "Octomom".

Sufjan and Serengeti were introduced in 2009, when they worked together on Buck 65's remix of Sufjan's cover of Castanets' "You Are the Blood" for the benefit compilation Dark Was the Night.

Serengeti will release the Kenny Dennis EP on Anticon on April 3. Watch the video for "Shazam" here.
