All The Blue Changes – An Anthology 1988–2003 is a double CD compilation by British Art Rock group No-Man, spanning their entire career – from the Speak sessions in 1988 up until the release of Together We're Stranger in 2003.

The version of "Days In The Trees" which appears on "All The Blue Changes" is a different mix of the "Mahler" version which made considerable impact when released as a single – it also features a longer fadeout than the other versions.

The version of "Dry Cleaning Ray" is a version of the single mix without a fade-out (running about 30 seconds longer), and "My Revenge On Seattle" is the unused alternate mix and edit made for a planned single release (before the band chose "Dry Cleaning Ray" instead).

Of the rare tracks, "Walker" dates back to the 1991 sessions for "Loveblows & Lovecries" and would have featured on the initial track list for that album.

"The Break Up For Real (Drum Mix)" and "(bluecoda)" both originally appeared on the limited-edition vinyl edition of "Together We're Stranger".
