In weaving America’s native culture and history, Philip Glass has created his own musical lineage. This album explores these ideas through his single most demanding piano piece, the ferocious, but lyrically meditative Piano Concerto No. 2 (after Lewis and Clark), as well as one of his most neglected, the mysterious A Secret Solo 2. Wichita Vortex Sutra, a joyful and transcendent study, is also heard in the version for narrator, with words by the poet Allen Ginsberg. From his experimental years comes Music in Contrary Motion with its mesmerising variety of pulse patterns.
