some ambient faves, not necessarily fit for purpose though:
Biosphere – Substrata
Alva Noto – Xerrox Vol1, Vol2 and Vol3
Aphex Twin – Selected Ambient Works 2
William Basinski – The Disintegration Loops
slowly getting on to Zomes a bit this year
and if you’re not familiar with Autechre I suggest you get started – right at the beginning with Amber, then see how far you get. Their latest (4 hour!) album elseq 1-5 is ferocious but still peppered with moments of outstanding beauty
