Trio X (Joe McPhee / Dominic Duval / Joe Rosen) - they toured several times in Europe, I should have arranged to see them live. I had reservations about Duval's style and neglected all opportunities to see him. I changed my mind now - he is excellent in the Trio X context.
Rob van den Broeck and Gerd Dudek - they were playing here in Vienna with European Jazz Quintet, and I missed them. Great musicians both.
Nicolas Simion, who just recently passed away. He played a few times in Austria over the last few years, not sure how I managed to have missed him as I am a long-term fan.
Michel Pilz, a great bass clarinet player. However, I am not sure how much he was playing live in the last two decades.
Heinz Sauer. I love the man, and had a chance to see him. He is 94 now, not sure if (and how) he is still playing.
Very little known Austrian band Kelomat with fantastic saxophone player Wolfgang Schiftner who does not seem to be active in music any longer.
And I wish I saw Pharoah Sanders in good form. The only time I saw him live - here in Vienna in 2011 - was unexciting.
