For example, a band like Joy Division. Two masterpiece albums in the form of Unknown Pleasures and Closer, and the untimely death of Ian Curtis cut it all short. They were even heading into the direction that New Order eventually went in, and it would have been interesting to see what Ian Curtis would have done if they fully made the leap into electronic music while he was still alive.
For any mid 2000’s metalcore fans out there I’m sure yall can agree that Catherine fits the answer to this question. Their album The Naturals was absolute perfection and then cancer had to be a piece of shit and take the vocalist from this world. Their follow up with a new vocalist, Inside/Out, had a couple of good songs but it just wasn’t the same. Always wondered what that release would have been like with their OG vocalist.
