Joan Tower is widely regarded as one of today's most important American composers. The works heard here in their world premiere recordings are part of a growing legacy that one pundit has described as "The Power of Tower." Strike Zones is tailor-made for percussionist Evelyn Glennie's dazzling technique and impeccable musicianship. The work's orchestration is crafted to enhance a stage filled with percussion instruments - while in Small they are contained on a single table, the soloist working like a brilliant chef. The piano concerto Still/Rapids was inspired by the glistening beauty and powerful force of water, and Ivory and Ebony, written as a test piece for an international piano competition, is infused with Tower's "high-energy" signature.
