GRAMMY GOLD:

Even before Bonnie Raitt enjoyed her Grammy sweep, her album had hit the platinum mark. But now her sales have gone through the roof. In the four-plus weeks since the Grammys, her album has sold an amazing 500,000 copies, catapulting her to No. 3 on the Billboard charts, easily the best showing of her career. It also gives her manager, Danny Goldberg, two Top 10 clients, with budding pop starlet Alannah Myles (who just had a No. 1 single) moving up to No. 6 on the album charts. . . . Artists heading the wrong way-- down the charts--include Kaoma, the ultra-hyped lambada band (which hasn’t cracked the Top 40), Joan Jett (whose “Hit List” covers collection is fading fast), DJ Jazzy Jeff & the Fresh Prince (whose “Mike Tyson” single bombed, sending the rap duo’s “And in This Corner” disc plummeting off the charts) and UB40, whose “Labour of Love II” failed to woo any pop fans with its reggae renditions of old soul tunes. But the year’s worst disaster, so far, surely must be Terence Trent D’Arby’s much-touted “Neither Fish Nor Flesh,” which never made it higher than No. 61 on the Billboard charts. The album was such a stiff that CBS never bothered to release a second single.
