The New Music Guild will present a gala concert as part of its Festival XXXIV on Friday.

Guest artists will include Wanda Sobieska, violin; Sho Omagari, violin, and Thomas Osuga, piano.

Sobieska has appeared as a solo and chamber musician in the United States, Poland and Canada, and has performed with several professional orchestras. She also is an arranger and has been commissioned to create arrangements for the San Francisco Chamber Orchestra and the English Symphony Orchestra.

In 2009, she launched www.freegigmusic.com, a website dedicated to making much-needed sheet music available to working musicians that features her own practical arrangements of commonly requested pieces.

Omagari, a graduate of Mannes College of Music and the Juilliard School of Music, recently completed requirements for a doctorate in violin performance at State University of New York at Stonybrook. He specializes in Japanese contemporary music and recently played his doctoral recital accompanied by pianist Osuga.

Osuga has been a respected teacher on the preparatory department faculty at New York’s Mannes College since 1994. He is the founding director of Aurista Chamber Music and frequently performs new works on concerts in major New York venues.

Youngstown State University Professor Emeritus Robert Rollin will direct the gala concert, which will feature three premieres — Adagietto for Strings, a slow, lyrical piece by Kent State graduate student Galo Arboleto Solzano; Suite for K No. 2, a minimalist composition in eight short movements by Westminster College faculty member Jason Tad Howard; and Rollin’s “Elijah, the Prophet,” a setting based on two Hebrew melodies with Sho Omagari as violin soloist.

The orchestra also will play Rollin’s “Fantasy on Polish Folk Songs” with Sobieska as soloist. It presents variations on the old Polish song “Sleep Sweet Little Jesus” (also used by Chopin in his B Minor Scherzo), alternating with songs from the Polish Carpathian Mountains that originally were collected by Sobieska’s grandparents.

The concert starts at 7 p.m. Friday at SS. Peter & Paul Church, Holy Apostles Parish, 421 Covington St., Youngstown. Omagari and Osuga also will give a violin and piano recital at 7 p.m. Saturday at First Congregational Church, 41 E. Jefferson St., Jefferson
