Some good news for anyone interested, the Suzanne Ciani quadraphonic recording, the one released on LP from 2017 in an edition of 270 with decoder that sold new for $270.00, appears on the Blu-Ray of the Ciani documentary âLife In Wavesâ with video and stunning quad sound (itâs listed on the cover as â2017 Quadrophonic Performance). I believe itâs the full concert. I noticed the Blu-Ray in a record store in Edinburgh. It is a DVD/Blu-Ray double set and is still in print (the quad concert is only on the Blu-Ray). It is great if you like synth and sequencer stuff. Some of itâs atmospheric/ambient, some is sequencer driven with synth wildly flying around you in quad (think Kraftwerk or moderately more experimental, strident Jean-Michel Jarre. Itâs pretty glorious and the discreetness is great). It is all done live on a Buchla synth with (for lack of the proper way of putting it) a quad sequence directing/directional pad and itâs a wild mix.
