Hmn, I've got an interesting suggestion for this week as well, though some might find it a challenge.
Mike Oldfield - Amarok (1990)
Far better than the ever-lauded
Tubular Bells IMO, this 60 minute, 1 track effort from the master of ambient-prog is Oldfield's finest moment. Like previous works, Oldfield is responsible for most of the eclectic instrumentation. Worldbeat atmospherics, stabs at synthwork which wouldn't be too far out of place in a Legend of Zelda game, insanely good guitar and bass and loads of percussion are but a few of the things you'll hear in
Amarok, but such is but a modest overview of how grand this suite is and I couldn't do it justice in 10 paragraphs, much less this one.
But basically, this is top class world-prog. fusion, and one of the 90's Holy Grails of prog. for those interested, so hope a few of you give it a whirl. xD
