There is uncertainty of when pianist John Tilbury recorded these three solo keyboard works by his associate and friend, legendary minimalist composer Terry Riley, performing "Keyboard Study #1" and #2, along with "Dorian Reeds" using piano, electric organ, harpsichord & celesta, captured with excellent quality in superb performances from Tilbury at the height of his powers.

Recorded during the 2013 Angelica Festival at Teatro Comunale, Terry Riley's 3 Generations Trio bring Riley on synth, piano and Indian influenced vocals together with son Gyan on guitar and Tracy Silverman on electric violin for an immersive and meditative performance.
