The cycle consists 6 concerti which are notoriously fitted on 2 LPs. Therefore the cocerti are pressed in alternated order to fit two of the shorter concertos on the same side. Still the sides that comprise 2 concertos are about 30 minutes long.
Releses on 3 LP:
Fitted on 5 sides, 6th side empty
Just a little warning, my copy which looks near mint, sound dynamically compressed and lacks sparkle.
