Ponderosa Twins Plus One, ‘Bound’ (1971)

Most of the production on Kanye West’s 2013 album “Yeezus” was harsh, electronic and futuristic (with the occasional nod to classic dancehall reggae). But with its loop of “Bound” by Cleveland soul group the Ponderosa Twins Plus One, the LP’s final track, “Bound 2,” looked back to West’s “College Dropout” days of chopped-up samples and ahead to his mining of reissue labels like the Numero Group in the Wyoming era. If you know, you know.
