Re: Echoes, by Pink Floyd
Tom, get yourself Max MSP. That, sir, is where we are today in terms of sound manipulation technology. Think of a sound in your head, Max can do it if you know how. I'm not there yet, I'm very much learning (and I left my damn compatible computer at Uni - running Linux right now) but it is an INCREDIBLY powerful bit of software. Complicated, but well worth it.
The Live at Pompeii version of Echoes is the best version. The ear screaming guitar part actually sounds like a flock of Valkyries on their way to Valhalla. It's from another planet and I've never heard anything quite like it.
