Haven¹t searched my database lately (or updated it), but I will estimate: Definite top: Evan Parker: total about 145 - 150, probably half as leader/coleader, rest as sideman Anthony Braxton: about 125 or more, probably 75% as leader William Parker, more than 100, probably less than 125; most as sideman Then there¹s a group around 60 ­ 70, mostly as leaders (Ra and Taylor aren¹t frequent guests!): Sun Ra Cecil Taylor Derek Bailey Charles Mingus T. Monk John Coltrane Peter Brotzmann Han Bennink (few as leader) Below that, a bunch with around 30 or more: Joe McPhee Ornette Coleman Zorn A v Schlippenbach John Stevens As for how much of it is still sealed ­ quite a few but there isn¹t anything I haven¹t heard. Many are things I¹ve heard elsewhere and decided I want to own for future. Right now, I¹ve got more $$ than time, so I look at the shelves as a retirement project.
