20 minute prog rock journey! A.R. & Machines was the krautrock vehicle of Achim Reichel, formed in the late 60s. This 1972 album, Echo, is a dreamy guitar-driven composition, filled with ambient strings and all the available delay, reverb, and echo effects. It’s a perfect autumn record for listening to while bundled up on the porch with headphones. Reichel’s former band, The Rattles, had opened for the Beatles during their final tour.
