Jazz circle met up, wanting Miles in Kind of Blue (8)
I believe the answer is:
electric
'kind of blue' is the definition.
(electric blue is a shade of blue)
I don't understand the rest of the clue.
(Other definitions for electric that I've seen before include "Causing suddent excitement - from generator?" , "Form of energy for lighting" , "Relic etc charged with current" , "as fans may be?" , "Type of chair, hare, shock etc" .)
