Agreeing entirely with some of the other reviews here, there are some nice tracks on these CDs but most simply don't go together, and frankly the mixing between some of the tracks is terrible.
The second CD, depite having some nice tracks on, comes across overall as dull and uninspiring, whilst the first is just a mish-mash of styles and poor cross fades.
This could have been a good CD for the collection, it sounded good on paper, but the execution leaves something to be desired. A disappointment.
You get the impression that the compilers are culling only from the latest big names as opposed to anything remotely effective. More worthy inclusions would have been lesser-known titles such as "Monastery of La Rabida" by Vangelis, "Always Returning" by Brian Eno or the soaring guitar of "Summit Day" by Mike Oldfield. Even as a J.M. Jarre fan, I honestly think the inclusion of "Oxygene 2" was misplaced - get a copy of his album "Waiting for Cousteau" and skip straight to track 4. You'll be so relaxed, you won't move for an hour!
In summary, it sounded promising on paper or in advertisements but I felt the selection was insufficient to be properly classified as 'chillout'.
