A short review and interview is in GQ Magazine. The new album is described as a "delight" and Billie Joe talks about how satisfied the band are:

[quote]We're very satisfied with this album. We love releasing new material, but we didn't want to rush. We put it out when we're sure it sounds like we want it to. What else? There are two-minute songs that could be heavier, but we avoided that. The duration of the songs fits the message we want to send. This is very direct, very primitive, very bright. In half an hour we convey that somehow, we've returned to our origins, to the sound we liked when we started playing.[/quote]
