The martial-arts epic The Man With the Iron Fists is the RZA's directorial debut – although, figuratively speaking, the beat wizard has been making kung-fu movies for as long as the Wu-Tang Clan existed. The soundtrack is not as evocatively cinematic as the Wu's greatest songs, but it's a tasty mixtape – a blend of vintage R&B, neosoul and hip-hop, featuring Kanye West, Pusha T and many Wu members. The Black Keys bring scuzz funk to "The Baddest Man Alive," setting a grainy-film-stock 1970s vibe that's sustained throughout – even when Kanye is bragging about jet-setting and name-dropping Kurt Cobain.

“All Along the Watchtower”

Jimi Hendrix got hold of Bob Dylan's early John Wesley Harding tapes and in late 1967 recorded a version of "All Along the Watchtower" with the Experience in London. Dissatisfied with that first development, Hendrix brought those tapes with him to New York in early 1968 when he began work on Electric Ladyland. Eddie Kramer, Hendrix's engineer at the time, told Rolling Stone that Hendrix "was still looked upon by his basically white audience as the mammoth black guitar hero. There was a constant fight within him to expand himself." Hendrix's successful take on Dylan's work has long been recognized by the songwriter. "I liked Jimi Hendrix's record of this and ever since he died I've been doing it that way," Dylan wrote in the liner notes to his Biograph box set. "Strange how when I sing it, I always feel it's a tribute to him in some kind of way."
