You understand my point though. They're the more accessible, mainstream, pop version.
Editors have one solid album. Interpol have a few good albums, but their first album is one of the best albums of the last 30 years. And they've got an amazing presence live.
If it's the closest these people can get to seeing their actual favourite bands live, I see no harm?
If in 25 years, there was an Interpol tribute band knocking around (very doubtful), I would probably go see them, for nostalgia's sake.
