People keep saying that LP is going in this "new" electro sounding direction, when really it's not that new at all! They've always had an electro vibe courtesy of Mike and Joe, but they've never exactly capitalized on it. Hybrid Theory was pretty big on electronics, but it wasn't the main focus of the album. Meteora also experimented with different sounds and landscapes, stuff like Faint and SIB shows a bit of that experimentation, M2M same, had the electronics, even if much less than its predecessors. I think they were just tired of emphasizing the rap / rock / metal sound they'd been labeled with, and wanted to show that they weren't JUST that. That's why for ATS they made their electronic side their main goal. I think now with four albums that showcases all of their already existing genres, they'll either play it safe or try something new entirely, something that wasn't on any of the current material.
