Band chemistry.
Band chemistry is a complex thing. Everyone has to want the same goal bad enough to forge forward through thick and thin. Rock history has proven that the vast majority of bands don't have this quality. And those that make it have it way more than anyone outside of that band could ever imagine. Through thick and thin. Through highs and lows. Despite outside interests. Beyond the yearnings of settling down and growing roots. Ignoring that there are far better meals than the fast food chains next to the motels. Closing your eyes to the brightly lit marquees that suggest you're better than the average everyday person. Sleeping through nights while strangers knock on your door. Caring more about writing the next song than seducing the beckoning groupie. Well perhaps not that one.
