Cool, I might actually like this. Really hope they just stick with one solid producer. Wish they would get rid of the spacey sounds all together - it's not Blink too me, being someone who grew up with Enema Of The State... But I'll have to just change with them.
If he wants to do something edgier then they should just use the new songwriting techniques they've been using on their more recent tracks, but keep the production more "power trio" punk rock (their bread and butter), don't add too much to whatever they can accomplish with just drums, bass, and guitar. That would be cool to hear from them at this stage in their careers. At one point he does allude to "not necessarily taking a step backward," which sounds like by edgier he's thinking the way their older albums sounded. if they can marry the new songwriting with the old sound, that would be interesting to hear.
