SLeeper lps of 70s....

Everybody has Fleetwood Mac, Eagles, etc...any sleeper or lost lps that come to mind? Geils Monkey Island is one....
it's not rock, but 'native dancer' by wayne shorter and milton nascimento has always seemed to me like a very overlooked LP. pretty easy to find in good condition, well engineered, and absolutely beautiful music - it's 'fusion', in the sense that it blends genres (Brazilian and jazz), but it's really just about two huge talents working beautifully together.

also: I'm not sure they qualify as 'sleepers' anymore, but Nick Drake's 3 LPs, especially 'Pink Moon' were beneath the radar for years. way ahead of his time, gorgeous and timeless music.

and: they were 'big in Europe' and under-appreciated at home, but the Art Ensemble of Chicago was doing their best work during that period. 'les stances a sophie', 'people in sorrow', 'jackson in your house', 'tutankhamen', 'phase one', 'fanfare for the warriors' are all amazing albums - once again: huge talents working in perfect synergy...

I was at two Art Ensemble of Chicago Concerts - one in Warsaw in late 70s and one in Chicago in late 80s. Concert in Warsaw (big auditorium) was beyond believe. They started an hour late because of electrical/equipment problems but played to 1:30AM (almost 4 hours) to compensate for that. People didn't want to let them leave. Since Lester Bowie death in 1999 I lost a little bit of interest. Without his cutting trumpet it just not the same. Not too many people in Chicago, where I live, know about Art Ensemble of Chicago - what a shame.

If you want a real sleeper,check out
Chilliwack "All Over You"
everything released by "Big Star" - Alex Chilton's band. Winner. Hands-down.

"...Before it broke up, Big Star created a "seminal body of work that never stopped inspiring succeeding generations" in the words of Rolling Stone,[1] earning recognition decades later, according to Allmusic, as the "quintessential American power pop band" and "one of the most mythic and influential cult acts in all of rock & roll"..."
