*According to the liner notes, Garden of Delights states clearly that "Scena Westphalica" was released in 1976. They also opine that, in addition to Zoppo Trump, "the other tracks on the compilation album, by the way, are not of any interest for progressive fans." I have not heard the album myself, but I'm inclined to believe them all the same. I'm going to guess then, that the Electric Mud Orchestra, while no doubt related to the 1971 band (and bass player Udo Preising was the owner of the label Förderturm and a member of Electric Mud - and later was in Zoppo Trump - hence the connection), is in no way musically similar. As of course the Electric Mud album itself is "of interest" to progressive fans.
