"Playing Bluestone" by Mike Adcock

True rock music:

"'Playing Bluestone' features eight improvisations by pianist and musical-stone expert Mike Adcock— tracks recorded using only bluestones from the Preseli Hills, the very same rock formation where the 'ringing rocks' of Stonehenge were selected, quarried, and transported from.

This album stems, in fact, from the desire to record, document, and share the timbre of the musical stones of Stonehenge."
