I agree about Stanko, definitely. Also, everything by Anouar Brahem is of a consistently high standard. Louis Sclavis has hit a rich seam too.
Other artists that have released strong albums are Misha Alperin, John Surman, Stefano Battaglia, Enrico Rava, Christian Wallumrod, Markku Ounaskari, Francois Couturier, Tim Berne, Michael Formanek, Giovanni Guidi and I could easily go on.
Any drop off for me has been in the last five years or so
