Replace Josh with Taylor and I'm pretty sure it's the same as it was before. I don't think losing the Farros hurt the band as much as fans like to believe it did. I'm also pretty sure they're tired of being asked about that. They've all moved on. Why can't you?
Because music, that's why. No two guitarists are alike. The new album will speak for itself.
Myself in particular, I was a fan of Josh's riffs, and am curious to hear what Taylor creates.
And, 2 years time is enough for them to have a different perspective on the Farro situation. Paramore's bound to give some magazine the exclusive on these details, and when they do, that shits gonna sell.
