Who Is Brendan O'Brien

Well for starters Brendan O'brien is the Fellow who Mixes and Produces a large variety of bands. His work is usually well known, yet it is hard to find info on him. If you have any info. Please email I need some info because he is relativley hard to find info about. The reason I am doing this is because I am interested in the sound engineering field and his work has stood out to me a lot over the years. so here is a very small and roughly compiled list of his work that is known to me I know there is more out there so add to it. Thanks to Brendan L, Chris Caleo from "Torn & Frayed" & Mike for their contribution.
