New to jazz, looking for a very expressive player

I’m new to jazz so I don’t know many of the ‘big shots’ or ‘classics’ in terms of players. I’m looking for some recommendations on jazz (guitar/piano) player that are expressive, though not necessarily virtuosos or technically great.

I’ve recently discovered Bill Evans and he blew my mind. Could you recommend others like him (both for piano and guitar)?

Thanks in advance for all your help.
