Poshek-Gladbach writes primarily for piano and harpsichord, both solo and in chamber, in a style that reveals the same craftsmanship characteristic of the composers of the 18th century he knows so well. Yet, his sound is unapologetically 21st century harmonically, structurally, and rhythmically. Yet, his work is surprisingly easy of the ears. His keyboard writing is not for the technically faint-of-heart.
Poshek-Gladbach is a Chicago-based composer. He began his music career as a piano/harpsichord performer specializing in the music of the 18th century. A second generation student of Ernst von Dohnanyi, his teachers include: Karol R. Welcelean, Thomas L. Yancey, Edward R. Thaden, George Shirley, Edward Kilenyi, John Boda, and Kirsten Broberg. After a serious illness made performance impossible, Poshek-Gladbach has devoted himself solely to the composition of New Music.
