When a documentary film about the Yoko Theory was shown at the 2004 Palm Beach International Film Festival, things certainly looked up for the four ambitious groove-makers. However, a few months after the film debuted, the band split up, relegating its intriguing mix of reggae, jazz, and hip-hop to the film and a lone CD. Once a staple of clubs like Respectable Street, the Lounge, and Dada, the Delray Beach-based foursome performed around town like clockwork, never falling into inactive lulls or taking long breaks -- or letting girlfriends mess things up as they did in the band members' previous groups (hence the Yoko Ono reference). This, of course, begs the question: Was an unhappy girlfriend responsible for their breakup? Not this time. The band had simply run its course, dying of natural causes and proving that the theory was, well, just a theory -- albeit one that made some damned fine music.
