Sting, Tina Turner, Steve Miller, Sade, and Kenny G highlight the 1993 Greek Theatre concert schedule, announced yesterday by the Nederlander Concert organization.The Nederlander-booked Pacific Amphitheatre plans to release the bulk of its schedule later. An April 16 show by Reba McEntire will kick off that venue’s season. The Greek announced the first blues festival at the venue, which will be held in September, date to be determined, featuring B.B. King, Eric Johnson, Buddy Guy and the Alligator Records All-Stars, with Koko Taylor, Lonnie Brooks and Junior Wells. Harry Belafonte will be the second inductee to its Wall of Fame, following last year’s honoring of Carlos Santana. Belafonte is the Greek’s record holder in number of performances and guests at the theater, performing 146 times before 615,268 attendees. General manager Susan Rosenbluth and Nederlander VP and head of concert booking Alex Hodges both expected the Greek to turn around from a slightly off 1992. “In 1991, the Pacific Amphitheatre had its best year ever when a lot of other (venues) were complaining,” said Hodges. “In 1992, we had our worst year ever, when a lot of others had good years and turned the corner. I’m not sure to what extent it’s turned around, but this year I believe will be strong.” Greek acts for May include Steven Curtis Chapman with Bryan Duncan (1); Sting with dada (8, 9, 11); Vikki Carr (14); Stylistics/Dramatics/Chi-Lites (15); the Allman Brothers Band (25); and the Reggae Sunsplash World Tour ’93 with Freddie McGregor, Inner Circle, Shinehead, Mystic Revealers, Tiger, Skool (29, 30).
