Three of the very best....
Three musicians I admire:
Ella Fitzgerald, Stevie Wonder, Peter Gabriel
Ella: for her facility to sing a vocal line as a solo which is at least as good as those of the instrumentalists around her. Brilliant example here: C Jam Blues Live at the Santa Monica Civic 1972, taking on all the instrumentalist. As she sang “you’re not gonna blow my voice tonight!”

Stevie Wonder: for crafting the most delicious grooves. Superstition is the most obvious example but the brass riff in the middle of Sir Duke is unsurpassed.

Peter Gabriel: for poetic quality of lyrics married to evocative chords changes and melody. Best example personally is “Here Comes the Flood”
