Soul music doesn't get any deeper than the sides James Carr recorded for Goldwax Records in the sixties. Carr's most famous song was the gut-wrenching ballad "Dark End of the Street." The raw intensity of Carr's vocals transforms a simple tale of forbidden love into a brooding meditation on the nature of danger and recklessness.

In a similar vein, there's "Blackjack" by Ray Charles; on the surface it's a slow blues about a gambler down on his luck, but Brother Ray's aching vocals transform the song into something deeper. There are a number of blues songs that convey a tangible sense of menace, making them all suitable for a movie about outlaw bikers.

Albert King's "Born Under a Bad Sign" combines hard-bitten lyrics with Albert's stinging guitar and a strong backbeat courtesy of Booker T and the MG's. On the opposite end of the musical spectrum is Junior Kimbrough's "You Better Run." Junior Kimbrough plays in a style called Mississippi Hill Country blues; his music is droning and hypnotic, with few chord changes.

One of Stevie Ray Vaughan's deepest, darkest blues tunes was the minor key workout "Tin Pan Alley." Any one of these tunes would make an excellent background for the Angel's many turf wars and run-ins with the law. In his autobiography, Barger describes the seventies as a "gangster era" for the Angels; Barger himself got heavily into drug dealing during that era.

No song better captures the bleak mood of America's inner cities-Oakland included- in the seventies than War's "Slipping into Darkness." The Neville Brother's "Brother Jake", "Gun" by Gil Scott-Heron and Marvin Gaye's "Inner City Blues" are other great examples of funk tunes that reflect the turmoil and violence of inner city life.

Of course, there's more to the life of an Outlaw Biker than crime, violence and jail time. These guys really know how to party; Hunter S. Thompson thoroughly documented this side of Angel life in his book. There aren't many people around these days who remember Mike Bloomfield and Nick Gravenites, but back in the 60s and 70's, they made some incredible music together. Nick had a gruff, soulful voice and wrote some great lyrics; Bloomfield was a guitar virtuoso. "Drinkin' Wine", Nick's ode to alcohol abuse, is one of the best tunes recorded by the short-lived sixties band Electric Flag. "Dancing Fool" is another great Bloomfield/Gravenites collaboration-it can be found on Bloomfield's Live at the Old Waldorf album. John Lee Hooker's "Boogie Chillun" has been recorded too many times to count, but the version he did with Canned Heat on the Hooker and Heat album has got to be the most Dionysian rendition I've ever heard of Hooker's signature tune. In my day, the ultimate soundtrack for any type of debauchery was the music of Parliament and Funkadelic. "Super-Stupid" and "Cosmic Slop" are two of my favorite songs by the more rock-oriented Funkadelic. Some of the more memorable tunes by the dance-oriented Parliament include "Up For the Down Stroke" and the anthemic "Give Up the Funk."
