Which artist/band has the longest discography where every album is essential?
To try and explain what I mean, on the one hand, I think there's a very strong case to be made that all five Police albums are essential listening for anyone with even a passing interest in music. On the other hand, I think most of us can agree that unless you're a diehard superfan, there's no reason to listen to all 40(!) Guided By Voices albums. So I want to know just how far such a streak can go. What band or artist has the most studio albums where not a single one should be skipped?
Edit: fixed a typo.
