Gospel of electronic keyboard player and composer is ignored (7)

I believe the answer is:

evangel

I'm a little stuck... Click here to teach me more about this clue!

'gospel' is the definition.
(I know that gospel can be written as evangel)

I cannot understand how the remainder of the clue works.

Can you help me to learn more?

(Other definitions for evangel that I've seen before include "Name applied to any of the four main Gospels" , "Gospel of the New Testament" , "Matthew maybe" , "good news for Christians!" , "moral doctrine" .)

I've seen this clue in The Independent.
