Query: A MASTERPIECE

THIS COLLECTION WAS YEARS AHEAD OF IT'S TIME, A SOUND UNLIKE ANYTHING GENESIS HAD EVER DONE PRIOR AND HAS YET TO BE REPEATED. IT IS AS ENJOYABLE TODAY AS IT WAS THEN AND HAS INFLUENCED A GENERATION OF MUSIC TO IT'S CREDIT. THIS IS A MUST IN ANYONES COLLECTION OF PURE PROGRESSIVE ROCK FROM THE 70'S AND IS STILL TALKED ABOUT ALL THESE YEARS LATER.
