For guitar, you’re definitely going to want Django Reinhardt. Totally unique technique, since he only really had one functional hand. If you ever see a photo of him, you’ll see it - the fingers on his left hand were so badly burned he couldn’t use most of them

Emily Remler is a personal favourite. Wes Montgomery. Gabor Szabo.

Piano…Art Tatum, Herbie Hancock and Dave Brubeck. PARTICULARLY for Brubeck, an album called Take Five. Duke Ellington was also personally a pianist, though he veers into big band sound more than the others I’ve named
