Arlene Elizabeth Sierra is an American composer who divides her time between the U.S. and Britain. Recent commissions demonstrate her dual-national profile, from organizations including the Tanglewood Music Festival (the Paul Jacobs Award Commission), the Performing Right Society Foundation, the Albany Symphony, and the Huddersfield Contemporary Music Festival (a commission for its 25th birthday celebration). Her chamber works are regularly commissioned by performers in the U.S., U.K. and Germany and her music for dance has been performed at Jacobs Pillow and Tanglewood, but most frequently in her home city of New York.

Born in Miami in 1970, Arlene Sierra began her musical studies at the piano at the age of five. She had her first composition lessons at Oberlin College - Conservatory of Music, where she earned dual B.Mus. and B.A. degrees in Electronic Music and East Asian Studies. Her education continued at the Yale School of Music where she received an M. Mus. in Composition, and at the University of Michigan, where she was a Merit Fellow and received a Doctorate in Composition. In America her teachers included Jacob Druckman, Martin Bresnick and William Albright. As a participant in composition seminars at the Dartington Festival and the Britten-Pears School in the U.K., she studied with Judith Weir, Colin Matthews, Oliver Knussen and Magnus Lindberg.

Described in the London Times as outstanding and vivid, Arlene Sierra's chamber, vocal and orchestral works have been performed by Aeolian Singers, the American Composers Orchestra, the London Sinfonietta, Psappha, the Albany Symphony, the Schubert Ensemble of London, and the Tokyo Philharmonic; performances at festivals have included Aldeburgh, Bowdoin, Fontainebleau, Tanglewood, Dartington, and Aspen.
