Jonathan Powell is a British pianist and self-taught composer.

Kaikhosru Shapurji Sorabji was an English composer, music critic, pianist and writer whose music, written over a period of seventy years, ranges from sets of miniatures to works lasting several hours. One of the most prolific 20th-century composers, he is best known for his piano pieces, notably nocturnes such as Gulistān and Villa Tasca, and large-scale, technically intricate compositions, which include seven symphonies for piano solo, four toccatas, Sequentia cyclica and 100 Transcendental Studies. He felt alienated from English society by reason of his homosexuality and mixed ancestry, and had a lifelong tendency to seclusion.
