For me, that means consistent interest over the course of a long career, because hearing the music evolve is part of the pleasure. On that basis, There are probably 4 that fit that bill above all others:
Todd Rundgren
Fleetwood Mac
Richard Thompson
Kid Creole
E/The Eels would have been the fifth, but their (his?) recent work has left me kind of cold.
