i don't think it's any secret as to how Bruce Swedien feels about using compression:
"Compression is for kids."
"Compression is a crutch. "
Swedien is an amazing cat - his resume is ridiculous; from Count Basie and Duke Ellington to McCartney and MJ... with many others in between.
Your first or second mix is probably the best...
Why is it so hard to say "I'm done" with a mix?
Is a mix ever really finished??
An interesting article from Pro Sound Web. It's apparently an excerpt from Bruce's book Make Mine Music.
