This 5-album collection is outstanding value: for around £12, you can acquire almost all the essential work of John McLaughlin's legendary MO in one package.
The first three albums `The Inner Mounting Flame', `Birds of Fire' and - recorded live in Central Park NYC in 1973 - `Between Nothingness and Eternity' feature the original virtuoso line-up of McLaughlin, Hammer, Goodman, Cobham and Laird. The later two albums feature line-up changes and the deployment of orchestral strings, and don't quite have the dynamism, the take-your-breath-away energy-burst of the first three. They're good, though, and important milestones of this busy period in the evolution of rock-jazz fusion.
The only conspicuous absence is the later-released `The Lost Trident Sessions' featuring the studio material planned for the third album, some of which is performed live on BNAT but which is otherwise unavailable; and the lesser known `Inner Worlds', from 1976. The inclusion of these disks would have completed the package, but you'll have to buy them separately.
Some reviewers have complained about mistakes and omissions in the sleeve notes offered with this package, a criticism with some merit. However, it's important to keep a sense of perspective. If you buy this package, you will acquire almost all the music of the greatest fusion band ever, on high-quality digital CDs, at an unbeatable price. If having the sleeve notes is important to you then get them off the web, or go buy the individual CDs separately.
Meanwhile, just listen: the production quality of the sound is exemplary, like the original albums, and at this price you can't go wrong.
