ELO or ELP?Is there any ELO that's not live that's available in some multi-channel format? I don't think I've seen any.
ELO's debut album was issued in quad. The quad mix is available on DVD.
Four ELP albums were mixed into 5.1: ELP, Tarkus, Trilogy and Brain Salad Surgery. (Two different 5.1 mixes of Brain Salad were released.)
