Mahavishnu Orchestra - Obscure?
AlChuck, you have to admit that outside of the dwindling band of Jazz-fusion fans, very few people today know who John Maclaughlin or the Mahavishnu Orchestra are(were). Just because this site is frequented by musicians who have long memories and dog-eared albums from thirty years ago (including me) doesn't make us representative of the population at large.
At work the other day, a few of us put together our personal top ten Albums of all time (hey, we're civil servants - what else are we going to do?) and each of us had stuff that none of the others had ever heard of, and we go back a long way, with pretty wide musical tastes - my point is that if you've never heard something, it's 'obscure' to you, even if the artist in question has some kind of reputation.
