I somewhat agree. I believe "Incantations" to be his finest work since TB I. In order, I'd list them as:
1. TB I
2. Incantations
3. TB II
4. Hergest Ridge
5. Five Miles Out
6. Platinum/Airborn
7. Ommadawn
8. The Songs of Distant Earth
9. Islands
10. Tres Lunas (latest; really not bad--sort of a sequel to The Songs of Distant Earth)
11. Discovery
Everything else is mostly worthless. A shame.
BTW, I characterize "Amarok" as "occasional flashes of brilliance separated by enormous wads of filler."
The next release is a completely re-done (from scratch) Tubular Bells I. It may already have been released in Europe.
It saddens me that they keep releasing old wine in new jars just to keep the royalties up.
