Why was this bumped after 2 years?
But I really enjoyed their first effort, so I'm also keen to hear this.
If you accept it as a mild traumatic brain injury, then by definition it would not induce a coma (loss of consciousness greater than 6 hours). If you take it to include any traumatic brain injury then it could cause a 20 year coma I suppose.
If it happened to me though, I probably wouldn't be looking for the next Pearl Jam to be honest.
