The U.K's Guardian newspaper has a good round-up of why George Martin mattered so much to what will probably be regarded as the greatest ever band.

ELO's Jeff Lynne said "George Martin is my favorite record producer. There were millions of questions I would have liked to ask him. It's so sad that I won't get to ask them now. I only met him a few times and I was always in awe of him. His productions were brilliant. He created his own sound."

Butch Vig credits Martin's methods as helping Vig himself to persuade Kurt Cobain to branch out in the studio. "He was very fastidious about how he wanted to hear things. Because everything had a great clarity to it. I can't tell you how many bands I have worked with who would bring up Martin's production techniques."
