A key feature of the "neo mainstream" movement and even certain projects from people outside that movement is to revisit jazz compositions and styles from past times. Honestly, I usually find these revisions or excavations a waste of time (or much worse), as the results rarely have the vitality and urgency of the originals.
Even the Art Ensemble of Chicago, for example, loses me on those Dreaming of the Masters recordings from the 1990s. The cover of Purple Haze, for example, is painful, in my opinion. (Zombie is pretty good as is Creole Love Call).
But there are and have been exceptions. When Sun Ra's band started playing Fletcher Henderson charts in the '80s I was blown away. I love what Steve Lacy and friends did with Monk tunes. The Duke/Strayhorn duets between Lacy and Mal Waldron are absolutely stunning. Duke's own tendency to reach back in his catalogue often had vital results, such as Ellington '55. David Murray, Henry Threadgill, Dave Burrell and some (some!) of Paul Motian's retrospective approaches really grab me. When I'm in the mood, Charlie Haden and Hank Jones' Steal Away works just fine. Dave Holland's bands echo various post-1960 (or so) compositional and improv approaches and his stuff is interesting. Tim Berne's post-modern cut and paste jumpcuts are often intriguing and seem more sincere and less gimmicky than Zorn's earlier work.
The tendency of a lot of the younger neo mainstream players to echo '60s Blue Note approaches (so-called "hard bop") is truly unfortunate, as the original recordings are always far more varied, energetic and natural-sounding. Why would I spin Donald Harrison etc. if I can just check out Turrentine, Blue Mitchell or Lee Morgan?
Here's a (very) short list of revival or back catalogue work I'd be interested to hear:
The Herbie Nichols songbook arranged for a quintet or larger ensemble. I think Rudd's groups used to include some Nichols tunes but I don't have any of those recordings. Perhaps an extensive excavation of Andrew Hill compositions with new approaches/arrangements as well.
A new and improved Skies of America; a better recording with a more enlightened and sympathetic orchestra and conductor.
Re-arrangements and performances of Cecil Taylor compositions for various ensembles.
Art Ensemble of Chicago compositions could be an interesting legacy in the right hands.
A revisiting of James Blood Ulmer and Ronald Shannon Jackson compositions for various formats. Jackson and Ulmer's groundbreaking work went by pretty quickly.
Somebody I admire having a go at a new arrangement of Dogon AD.
Just some thoughts. The Vandermark 5's "Free Jazz Classics" really didn't do it for me, to put it mildly, but that doesn't mean there isn't potential for relevant and vital contemporary stuff to be done using a more judicious and less "corporate bopper" approach.
