Live at the 1988 Montreux Jazz Festival.
I can thoroughly recommend this package. 2 CDs and a DVD of the concert with additional interviews. Not only does it feature Carlos and Wayne, but they're backed up by a superb array of musicians including patrice Rushen and Ndugu Chancler, namechecked in the willie nelson thread, and featuring Alphonso Johnson on bass. Watch out for Jose Chepito Areas on percussion, The smallest guy with the biggest hair;-)
No Alembics but some very fine musicians.
