How about Mike Olfield Tubular bells 1&2 is this considered Jazz ?
this was considered a classic for its time ,what category is that in ?
No, no, no!
Not even close to jazz.
It is firmly in the prog-rock genre, or progressive music genre. which is such a broad genre of music, with some of the widest variation in any musical genre I know of.
While several subgenres of prog are highly influenced by jazz, and may even be as much jazz as prog, Mike Oldfield is certainly not.
For example: the Zeuhl subgenre of prog, started by a drummer, Christian Vander, who idolized John Coltane. And that core of jazz tends to run through many bands that are in this subgenre. Or, the so called Canterbury scene of prog, has much in common with jazz fusion.
