Tokyo producer Calm supplies a steady shore's lapping of sound with his next album, Ambient Jazz, not far after his previous records Before and Quiet Music Under The Moon. After a period of sharp emotional whiplash, Calm sets in again to moll the nerves here, serving a full plate of smooth new age and sonic draperies, recalling the night time jazz chasms of John Hassell especially. Between prefectures Tokyo and Yamagata, trusted collaborators are once again folded in, Calm asking them to prioritise tone over improvisation; saxophonist Kato takes central improv stage again on the plainly titled 'Jazz Acid 2' and 'After Dark', while deeper sus-chord shades stark jazz on the likes of 'Space Ritual'.
