Mark LaFratta had a brilliant idea of compiling and arranging extracts from the slow movements of three late Beethoven String Quartets and titling them Drei Mehr Equali (Three More Equali) for Four Trombones. They are beautiful and fit into the equali style of the 18th Century. They are scored as the original equali for alto trombone, two tenor trombones, and bass trombone. -the publisher
