The dark Chris Squire as someone put it, Ray Shulman played some amazing basslines for Gentle Giant. Punchy and complex but groovy and with a great sound.
The single they apparently hated:
More commercial from the later years but the bassline in the chorus is a bliss.
Ray was and is also a great guitarist and violin player. From "Octopus" (1972) onwards he used mainly a Fender Precision, played with a pick.
