You meet the third member

You are driven to Isaac Arnie's place. A nice stately home owned by his father. He comes out with a fairly nice foldable midi drum kit that he shoves into the trunk. You don't remember a thing after that until you wake from your coma three years later. You got into a car wreck it turns out The band says you are still a member. But they have put out two albums without you, both of them regional hits.
