You got it, Will. I may get this really mangled but ... He's an engineer out of MIT and he formed Boston because he had so many ideas about guitar sound and music production. He's also really fond of the organ. I don't think he was ever "fired" since he was really the founder although I bet the record company had issues with him. After "Don't look back", he spent more time on guitar effects and processors under the name Sholtz Design *something*. He basically put the signature Boston guitar sound (clean distortion and chorus/flange) into these little boxes.

"Third Stage" came out because of the huge demand for another album and I believe they are working on a fourth.
