Back in 2017, it was announced that Esoteric had picked up the rights to part of the vast Warner Music back catalogue, and the first fruits of this (with plenty of really exciting re-issues including Barclay James Harvest, Be-Bop Deluxe and Chris Squire) were the remasters of the Curved Air back catalogue from the early 1970s. Those special edition remasters of the first four albums are condensed into a 4-disc clamshell box containing Air Conditioning (1970), Second Album (1971), Phantasmagoria (1972) and Air Cut (1973).
