Dave's vocals were recorded at a lower range and then sped up for the vocal track on Welcome to the Machine. Perhaps that is why they sound unnatural. Dave could never reach those registers naturally.

I think the vocals on that track match the theme of the song nicely--they are mechanical and dry. In addition, I think the vocal styles match the throbbing of the VCS3 to give the song a very dry, if not futuristic tone.

I was never a fan of Welcome to the Machine until recently. I love Mr. Wright's keyboard work on it! The combination of the VCS3 and Arp Solina String Ensemble is quite pleasing; especially thank funky echoed solo at the end. Hats off to Mr. Wright on this one. Why didn't he get a writing credit on Machine? I am sure Mr. Waters didn't come up with those amazing synth lines!

May echo be with you,
