This song marks the first time I ever blew on a guitar. I put the guitar down on the ground near the amp to get a humming feedback, as opposed to a squealy one, and blew across the strings in rhythm with the drums. There's probably some obscure Mississippi blues guitarist like 'Blind Lemon Pledge' who's done that before, but "Flower" is the first time any rock band had recorded the sound of someone blowing across the strings. It sounds like a sitar.〔Gilbert, Jeff. ("Primecuts: Kim Thayil" ). ''Guitar School''. May 1994.〕
