Polish Composer Coming.

Witold Lutoslawski of Poland, whose works in the past ten years have placed him among the most important composers of the century, will be one of three composersin-residence at the Hopkins Center next summer.

He will participate in the music festival of the fourth Congregation of the Arts. This nationally acclaimed summer music program is planned and directed by Mario di Bonaventura, director of music for Hopkins Center. Professor di Bonaventura also conducts most of the twice-weekly concerts.

Mr. Lutoslawski will conduct and supervise performances of his works in four concerts and present a series of lectures. Major works by Mr. Lutoslawski include the "Symphonic Variations," "Concerto for Orchestra," "Funeral Music," "Jeux Venetiens" and "Trois Poemes d'Henri Michaux."

The composer also has accepted a Hopkins Center commission for a work to be premiered during the 1966 Congregation. This is one of several new works in a major commissioning program instituted by Mr. di Bonaventura, the first venture of its kind among academic institutions.

The range and scope of the program is indicated by a list of some of the composers who have accepted commissions - Grazyna Bacewicz, Tadeus Baird, Robert Russell Bennett, Boris Blacher, Easley Blackwood, Carlos Chavez, Ross Lee Finney, Alberto Ginastera, Milko Keleman, Ernst Krenek, Mr. Lutoslawski, Vincent Persichetti, Walter Piston, and William Sydeman.

Mr. Ginastera will write a cello concerto. Mr. Chavez is composing a work called "Soli No. 4." Mr. Bennett has completed a work for band. Mr. Krenek's "Fibonacci-Mobile" was given its first performance last July.

Mr. di Bonaventura anticipates that six new works will be premiered at the 1966 Congregation of the Arts. Mr. Sydeman is expected to conduct his new viola concerto, and Alfred Genovese will introduce an oboe concerto by Easley Blackwood.
