Faces In Reflection, a solo-album by George Duke released in 1974, is available for download here. The album hasn’t been re-issued on CD yet. Duke had this to say about it:
I actually like this record. This was the first LP that really said what I wanted to say. The idea was to play intense music and use the voice as a tool for orchestration. (…) I began experimenting with odd time signatures and various synthesizer textures. This was my first solo record using a synthesizer.
In 1947, William Malloch, possessing a sense of history, recorded Igor Stravinsky rehearsing his new revision of his “Symphonies of Wind Instruments in memory of Debussy”. The sound is antique but the picture of what Stravinsky is striving for musically comes through clearly enough.
