This was originally mixed in Dolby Surround & released in stereo with Pro Logic encoding. The source for this were stereo FLAC files which I decoded into multi-channel & then applied virtual surround for this stereo mix-down. This gives 3D surround with ordinary stereo headphones. This long-awaited release features Stuart Milligan as Superman, Shelley Thompson as Lois Lane, William Hootkins as Lex Luthor and Bob Sessions as The Batman and was written to celebrate Superman’s 50th birthday.
