I'd say it's much more like going from jamming on weekends with your friends to writing and recording an album, then taking it out on tour. You have to line up radio promotion, online fan community building, potentially a video or three, magazine interviews, contests, backline... you can't just do one thing and expect everything else to fall into place.

Every band is a complex business that has to get really good at managing multiple moving parts while entertaining people with great songs.
