OPERA PLANS OUTLINED BY HEMMINGS

With the first three Los Angeles Music Center Opera productions of this season already on display, executive director Peter Hemmings outlined the company’s plans for the next two seasons at a press conference Friday.

Of particular interest was the company’s 1988-89 season, tentatively budgeted at $7 million and boasting five new productions of a total of seven. They are:

--Mozart’s “Cosi Fan Tutte,” with Carol Vaness, Ann Howells, Jeffrey Black and Stafford Dean, conducted by Christopher Hogwood and staged by Sir Peter Hall.

--The double bill of Mascagni’s “Cavalleria Rusticana” and Leoncavallo’s “Pagliacci,” with Julia Migenes-Johnson (in “Pagliacci”), Domingo and Peter Glossop (in both operas). Conducting is Garcia Navarro. The production will be staged by Frank Corsaro and designed by Franco Collavecchia.

--A production in English (using no supertitles) of Janacek’s “Katya Kabanova.’ Karan Armstrong will sing the title role, with her husband, Goetz Friedrich, directing. Jiri Kout will conduct.

--Berg’s “Wozzeck,” with Simon Rattle conducting the Los Angeles Philharmonic, will have Benjamin Luxon as the unhappy soldier and include Elise Ross (Mrs. Rattle), Warren Ellsworth and Thomas Stewart in the cast. David Alden is the stage director.

--Verdi’s “La Traviata,” conducted by Domingo and sung by Lucia Aliberti and Justino Diaz. No tenor has yet been announced.

Also included in the 1988-89 season are a co-production with the English National Opera and Houston Grand Opera of Offenbach’s “Orpheus in the Underworld,” designed by English cartoonist Gerald Scarfe and sung by Evelyn Lear, Thomas Stewart and Francis Egerton; and a revival of this season’s “Otello,” with Domingo returning to sing the title role and Ilona Tokody as Desdemona. The “Orpheus” performances will be given in the Wiltern Theater. All others will be performed in the Dorothy Chandler Pavilion, site of the press conference.

The 1987-88 season--most of which has been previously announced--is budgeted at approximately $6 million and will be augmented by one operetta: an English National Opera production of Gilbert and Sullivan’s “The Mikado,” featuring Donald Adams, Marvellee Cariaga and Alice Baker. Adams, one of the title role’s leading exponents for the past 30 years, will instead sing Pooh Bah in this production, which will be staged by Jonathan Miller and will be presented in the Wiltern Theater. The roles of Ko-Ko and Yum-Yum remain uncast.

Also on the ‘87-’88 season schedule are new productions of Rossini’s “La Cenerentola,” with Frederica von Stade in the title role and Sir Neville Marriner conducting, and Wagner’s “Tristan und Isolde,” with William Johns now scheduled to sing Tristan opposite Jeannine Altmeyer.

The addition of Johns completes the casting of the delayed production, once projected for this year when Domingo, the company’s artistic consultant, was considering singing Tristan.

As was previously announced, Zubin Mehta will conduct the Los Angeles Philharmonic in the Wagner performances. The production will be designed by David Hockney and staged by Jonathan Miller.

The previously announced Lady Macbeth, Mara Zampieri, will be replaced by American soprano Linda Roark Strummer in next season’s “Macbeth.” Zampieri was withdrawn from her Metropolitan Opera debut last season without explanation and has subsequently canceled all her American engagements. No reason for her cancellation here was offered Friday.
