WINDOWS is a live album by Jon Lord and the German conductor/composer Eberhard Schoener. It was recorded at a concert in Munich in 1974, and the music is a mix between progressive rock and orchestral late romantic/modernist styles. It features musicians from the rock world, such as David Coverdale and Glenn Hughes. Dark Horse Records is celebrating the 50th anniversary of Windows with a limited-edition orange crush color vinyl pressing. "Continuo on B-A-C-H" is a loose attempt to build on the unfinished triple fugue that closed Johann Sebastian Bach's "Art of the Fugue." The second side of the LP is a three-part composition called, "Window." Ray Fenwick (The Spencer Davis Group, Ian Gillan Band), Tony Ashton (The Remo Four, Family), David Coverdale (Whitesnake, Deep Purple), Glenn Hughes (Deep Purple, Black Sabbath), and Lord himself, perform as soloists along with the Munich Chamber Opera Orchestra conducted by Eberhard Schoener.
