I just ordered his Mosaic cds from an Amazon seller, so I'm looking forward to hearing more of him.
For me, Bechet was the definitive traditional clarinetist ("Blue Horizon" is, for me, THE great clarinet performance), Goodman the greatest Swing clarinetist, and DeFranco the greatest bop one. Of more recent clarinetists, I like Eddie Daniels (especially the Goodman tribute album he did with Gary Burton). Anat Cohen is interesting. I'm listening to her. And yeah, Prez played really cool clarinet...when he played it.
