Fusion Fusion jazz — a genre popularized in the 1970's, but more recently derided — is enjoying a revival. The four-CD reissue of Miles Davis' "Bitches Brew" has sold 70,000 copies so far. That's prompted Sony Music to unleash a slew of other stuff from its fusion catalogue. Fusion seems to have found a new audience among jam band fans. Re-issues include CD's from the bands Weather Report, and Return to Forever, as well as the Mahavishnu Orchestra. Tom Vitale has the story. (7:30)NOTE: STATION BREAKS BEFORE AND AFTER THE VITALE PIECE WERE TAKEN FROM THE CD "HEAVY WEATHER" BY WEATHER REPORT. THE FIRST SELECTION WAS "TEEN TOWN", THEN "HAVONA". THE CD IS #CK 65108 ON COLUMBIA RECORDS, REISSUED IN 1997.
