Recommend something that sounds like Globe Unity Orchestra's Hamburg '74

Of course, there are the Alexander von Schlippenbach trio, especially recommend Pakistani Pomade.

Italian Instabile Orchestra is first-rate. Litania Sibilante or Italian Instabile Festival: Pisa Teatro Verdi, December, 1997 is where I'd start.

Going back in the day: Communications--Jazz Composers Orchestra of America (features Cecil Taylor, Steve Lacy, Bley, Mantler, Pharoah, Jimmy Lyons, Don Cherry, Ed Blackwell, Andrew Cyrille, Jimmy Knepper, Howard Johnson, John Thicai and about ten other equally luminary).

Gunter Hampel Group-Music from Europe (featuring Dolphy).

Don Cherry's Blue Note trilogy: Symphony for Improvisers, Complete Communion, Where is Brooklyn?

Sun Ra-Live at Donauschingen
Archie Shepp-Live at Donausshingen

Alan Silva and the Celestial Communications Orchestra--Seasons (one composition over three lps or 2 cds now) featuring 20 or so of the prime avantgarde.

Joe McPhee--Nation Time (it's got nothing to do with Globe Unity, but it is a free jazz masterpiece).

That should give you some avenue of exploration.

I believe that's what the thread starter was asking.

Still surprised that no one else has tried to mix jazz with these big operatic vocal parts. I guess it costs too much.

The instrumental parts prob work up a racket but I'd have pull it out.

I wouldn't say the problem was money - the fact that Globe Unity and some big projects got off the ground to start with would go against that - maybe it's more to do with finding the right (gospel, I would guess) choir that would be willing to spend the time in adopting whatev novel techniques migth be required, and whether they'd accept this.

Penderecki wrote a piece for Globe Unity early on which moves among composed sections written in his early styles and free improvised sections. I recall that in at least some of the contrasting sections only subsets of the ensemble performed.

There was also a large ensemble work by Lester Bowie called Getting to Know Y'all which involved a mixture of European and mid-Western US (Chicago & St Louis, I think) musicians in a loosely formed suite.

Also, some of the JCOA recordings might be worth looking into, particularly the Clifford Thornton and Don Cherry LPs.

I don't know for sure about the current availability of the first two recordings, which came out on European labels (MPS Saba?), but it sure would be great if the JCOA discs that followed the Mantler & Bley sets would be released on CD sometime.

Speaking of JCOA, I still have yet to hear the Mantler JCOA. I know it's sort of an ilx fave, as it's on many free jazz threads. I will definitely try to track down that Lester Bowie album. I'm also really unfamiliar with most of Carla Bley's big band type stuff.
