the album title is named after a medical theory concerning increasing brain blood volume in order to enlarge awareness in sensitivy and empathy; in an interview with james bonisteel, the band described the album title: "well, there's a certain school of theory--a medical theory--that thinks if you increase the volume of blood in the brain that you can increase your awareness in your empathy and your sensitivity. there were some people in the 60's who tried to increase their brain blood volume by drilling a hole into the skull to crack sort of a pressure release. i don't know how crazy it is. people are trying to do that to themselves all the time, maybe not like that literally, but that's what people use drugs for and that's why people exercise--basically to release the pressure that's in them. i think it's something that everybody does in their own way; it's just that this is a particularly interesting way to relieve the pressures in your head."
