AND WAIT, THERE'S MORE: Crack is the drug of media renown in America, but in England the scourge these days is heroin addiction. With that in mind, a host of British rock luminaries have produced an album titled "Live-In World," due out in November, with all proceeds going to the Phoenix House, a London-based drug rehabilitation center. Stars on hand to record a new single for the album included the Thompson Twins, Howard Jones, John Paar, Nik Kershaw, Ringo Starr (and son Zak), Bonnie Tyler and many others. Other popsters, including Paul McCartney, Eurythmics, Elvis Costello and Bananarama have either written new songs or donated hits to the record (Costello's tune, which is not on his new album, is titled "Nothing at the End of the Rainbow"). . . . Closer to home, if you really want to dive into the computer age, we suggest a visit to LACE's upstairs performance gallery tonight at 8 for an evening of music composed and performed on the Macintosh computer. The gallery, located downtown at 1804 Industrial St., will include presentations by Michael Intriere, a founding member of the group FAFU; Keith Levene, a founding member of PIL, and Mark Wheaton, who has performed with Johanna Went and Bent. . . . Paging Cream fans: Drummer Ginger Baker, who has spent the past several years working his olive farm in Italy, returns next month with a new album on Celluloid Records titled "Horses and Trees." Produced by Bill Laswell, it features Baker and an eclectic group of musical pals, including Bernie Worrell, L. Shankar and Nicky Skopelitis.
