Ira Gitler

• "As he learned harmonically from Davis and Monk, and developed his mechanical skills, a new more confident Coltrane emerged. He has used long lines and multinoted figures within these lines, but in 1958 he started playing sections that might be termed 'sheets of sound'."

Nat Hentoff

• "While he was with Miles, Coltrane was tagged with the phrase "sheets of sound." Jazz critic Ira Gitler had first used it. These "sheets of sound" were multinote hailstorms of dense textures that sound like a simultaneous series of waterfalls. "His continuous flow of ideas without stopping really hit me," Gitler said. "It was almost superhuman. The amount of energy he was using could have powered a spaceship."
