The Utah Symphony's 59th season will be one of variety, according to music director Keith Lockhart.

"I have a wide range of interests," Lockhart said during a telephone interview from his home in Boston. "And between Maestro (Pavel) Kogan and Maestro (Joseph) Silverstein and I, there was a lot of planning done."

The schedule for the 1998-99 season was announced by Lockhart as he anticipates his first season with the symphony.

While the soloists and other artists had already been chosen by the time Lockhart was named music director in January, the conductor said the selections weren't confirmed until a few weeks ago.

"In an orchestra like the Utah Symphony, a balance is important," Lockhart explained. "And Maestro Kogan comes from a different culture and age demographic than me. So I feel confident we already have a built-in range of programming."

Lockhart said the season will encompass six series - Masterworks, Chamber Music, Family, Youth, Pops and Specials - all with various artists and selections that will appeal to everyone from first-time to veteran symphony subscribers.

"We are working with solid standards and getting more obscure works from the masters in," Lockhart said. "This year is the 100th anniversary of George Gershwin's birth. And instead of performing `Rhapsody In Blue,' we decided to do the full concert version of `Porgy & Bess.'

"We are also going to perform the seldom-heard Symphony No. 2 by Mendelssohn, which is one of my favorite works, and one by Bartok (Dance Suite)."

Likewise, Lockhart said, there are some selections that deserve the big "splashy" treatment.

"The Wagner selections and Holst (`The Planets'), which will open the season are always exciting," Lockhart said.

The season will also feature a world premiere, the conductor said. "We will performa work by Dan Welcher fittingly called `Zion,' " Lockhart said. "The selection was inspired not by what can be thought of as biblical reference but of the majesty of Zion National Park. I do believe it will be greeted with great interest by the Utah audience."

The upcoming season is, of course, Lockhart's debut, and he is anxiously looking forward to working with the Utah Symphony.

"I can't wait to start in full," Lockhart said. "And I'm anticipating some good things in 1999 and 2000."

- MASTERWORKS SERIES HIGHLIGHTS include Maestro Lockhart conducting the symphony with guests such as pianists Misha Dichter (Liszt's Piano Concerto No. 2), Garrick Ohlsson (Dvorak's Piano Concerto) and Angela Hewitt (Ravel's Piano Concerto in G Major), violinist Vadim Gluzman (Sibelius' Violin Concerto) and the Utah Symphony Chorus (Gersh-win's "Porgy & Bess," among others).
