READERS' PICK: You had better do what you are told; you better listen to the radio! And you'd better listen to KXCI, the best station in the known universe. On the air since 1983, KXCI plays the most eclectic, eccentric, electrifyin' rock 'n' roll you can imagine (and even some that you can't): world beat, roots, rockabilly, ska raves, obscure Grateful Dead live shows from 1971, lounge music, hip hop, psychedelia, country, Western, jazz, post-modern alt-emo trance fusion and so much more. Special mention must be made of KXCI's ongoing commitment to Tucson musicians; local artists are frequently played on the station, and often participate in live broadcasts. Although all the shows and DJs are thoroughly enjoyable, nothing, in our opinion, can compare to the powerhouse Saturday lineup: alternative acoustic music, followed by bluegrass, Ruby's Roadhouse, Kidd Squidd's Mystery Jukebox, Espresso Swing, Blues Review, Cafe Soul, Beat Street and, finally, the Live Jazz Show.
