After Sir George Martin passed away, all ears were on what remaining Beatles Paul McCartney and Ringo Starr would say. Now, it's the turn of fellow producers.

George Martin 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.

Current production star Mark Ronson said, “The very idea of taking a three-minute pop song and having the urge to put something more sophisticated on it – a string arrangement or a harpsichord or a choir – he brought that to pop music. I was in a studio last night with a bass in my hand, thinking, ‘What would George do?’ Every day you go in a studio, what he did with the Beatles is hanging over you as a barometer of trying to make a good song an extraordinary one.”

Gibson-playing Bernard Butler, ex-Suede but now more known for his lavish production work, says, “What George Martin did that was important was to say, ‘What if?’ That’s the biggest question a producer can ask. That’s what he gave all the mugs like me who came after: what if you take something and make it something else? George Martin took a group, a rock’n’roll band, four scruffy blokes in a room with primitive instruments, and thought, ‘What could you do with these personalities?

“But because he was seen as such a straight, jolly English fellow, the genius of his imagination gets overlooked. If he had worn shades and had the right haircut, he might be seen in an edgier light.”

It's a good point listen to The Beatles “A Day In The Life”. Essentially, it's two separate songs by Lennon and McCartney spliced together, with Martin recruiting a 40-strong orchestra to make it work.

Martin himself remembered, “What I did there was to write the lowest possible note for each of the instruments in the orchestra. At the end of the 24 bars, I wrote the highest note... near a chord of E major. Then I put a squiggly line right through the 24 bars, with reference points to tell them roughly what note they should have reached during each bar... Of course, they all looked at me as though I were completely mad.”

ELO's Jeff Lynne said “George Martin is my favourite 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.”

Radiohead, Beck and Paul McCartney producer Nigel Godrich summed it up. “It's the end of an era.”
