An impossible task. Here's what comes to mind for favorites, and this would probably change week to week.
-John Coltrane - Blue Train (One of my earliest Blue Notes so maybe a nostalgic pick. Listened to this for the first time in ages recently and still floors me.)
-Baby Face Willette - Face to Face (Wish he had recorded more.)
-Lee Morgan - Search for the New Land (I go back to this one often)
-Wayne Shorter- JuJu (Same as above comment, a masterpiece.)
-Sam Rivers - Fuchisa Swing Song (No a bad debut and of course his other Blue Notes are not to shabby.)
