I can think of maybe two musicians who might be said to fit in that tight intersection.

Brian May (guitarist from Queen) who has an astrophysics PhD from Imperial College London

Professor Brian Cox who teaches Physics at Manchester University and is a public face of science of tv here in the UK was keyboardist for one-hit-wonder band d-reem who had a hit in the 90s with “Things can only get better”.

Brian May is really the only one who is a superstar musician but Brian Cox is a more significant scientist.
