Both times I've tried "Crazy Train" on pro expert guitar, I've had such a visceral feel for what I was playing, It challenged me to play more precisely than I could ever on my own, and the sense of accomplishment was equivalently fulfilling.
So if we can simulate this environment where fresh, radical and crazy ideas are welcomed, encouraged, and have breathing room before they run into the emotional reaction train of someone else, then theoretically we may allow for more volume of ideas and more serendipitous exchanges.
