Very attractive music
This is nice music, not quite like Riley's earlier, more repetitive works, but a series of improvisations that include repetition and other modernist riffs. There's a lot that recalls Harold Budd, as well as the "new age" piano music - it's no surprise that it's on this label, but it's far from being new age music. It tends to drift a bit, perhaps going on for too long without direction, but it's certainly one of Riley's more attractive albums. The tuning is, as other reviewers say, just intonation. This is, of course, nothing new, and anyone who listens to early music is probably familiar with this, and has heard it on some harpsichord recordings. It adds a pungency to the music at times, and some listeners may think the piano is "out of tune".
