There was always quite a few similarities, they both had the whole Californian melodic hardcore with vocals soaring over the music thing going on (and in Pennywise's defense they have never made any bones about the debt they owe to BR). But Pennywise went more skate punk and you never needed to break out the dictionary to understand their lyrics. I have to say, the tracks I listened to from the new album sounded just like Pennywise did the last time I heard them, no more Bad Religion and no less. Admittedly I didn't listen to any all the way through since I was only checking them out through curiosity but still, it didn't sound like they'd changed the formula much at all. A little slower than the old days but that's been the case for a few albums now I think.
