Judging by the frantic crowd reaction in this video, Kanye West's big gamble appears to be paying off -- big time! Onstage this weekend at Los Angeles' Key Club, honoring the release of T.I.'s Paper Trail, West rapped alongside the Atlanta emcee on "Swagga Like Us" before revealing the November 25 release date of his new album, 808s & Heartbreak, and diving into its hit single, "Love Lockdown." What's more, West performed the album's second single, "Heartless," a head-bobbing, bass-heavy cut featuring a sampled chorus and highlighted, as always, by his mix of crooning vocals and slick rhymes.
