Another vote for Steve Lacy .... his solo Thelonious Monk introspections are treasurous .... btw witnessed with forum member "blacksaint" David Murray solo @ Jazzgalerie Nickelsdorf in the early 1980's, resulting in an unforgettable experience ....
Although integral part of some widely acclaimed recordings (Keith Jarrett's "European Quartet" comes to my mind) he seemed comparatively underrated .... btw saw him inter alias with Michel Petrucciani and Sun Ship Theus @ Wiesen Jazzfest in 1983 - was interesting to watch him being spured even more by an extroverted drummer ....
Alfredo "Chocolate" Armenteros "Chocolate En Guajira" (Caiman Records) 1983 .... a perfect showcase for the trumpet star ..... and Mariano Rivera on baritonsax shines too ....
