If somehow you encounter John "the Cop" Eischen and his trusty sidekick Jim "the Other Guy" Harrison playing somewhere that doesn't have a cheap happy hour, wake up and rub the crust from your eyes. You must be dreaming. Guitarist/singer John the Cop and fretless bassist the Other Guy are built for comfort, not speed, and they're built for bars, not theaters, convalescent centers, or gazebos. No, this old (John the Cop recently retired from the Fort Lauderdale police force) Delta blues duo know each other and their loyal, hard-partying fans well enough to know not to mess with a good thing. So one John the Cop and the Other Guy set is pretty much the same as any other, with Robert Johnson, Peatie Wheatstraw, and Muddy Waters tunes served up well-marinated and warm. The sharp, sprightly sound John wrings from his six- and 12-string resonator guitars is so authentic and pure that it practically ensures that you stay until last call. The day these two start doing shows at Starbucks next to the frappuccino and vanilla lattes or inside some snooty wine bar, best check your watch: It's probably time for the world to end. Until then, find 'em at the Downtowner Saloon or the Poor House in Fort Lauderdale. Right where they should be.
