anyone know dolo coker? virtually impossible to find jazz pianist. i bought an unopened vintage lp of his ('All Alone') because i liked the cover and i cant turn down virgin vinyl (for five bucks) and it wound up being a total score.
Francy Boland/Kenny Clarke "Now Hear Our Meanin'." Screaming Big Band European style.
