With this particular final 4, you know that Rock Night is going to be interesting -- and they don't disappoint. Adam and Allison are definitely suited for this, while Kris and especially Danny have a bit of an uphill battle. Slash is the mentor, which sounds exciting, but we don't really see a whole lot of him. I have no idea if this is what actually happened or not, but we definitely get the impression that he didn't work with the contestants as much as some of the other mentors did.

Also this week we have something new: duets. Frankly, I thought the idea was going to be kind of a train wreck, but they turned out to be really interesting. Pairing Allison and Adam together makes sense, but it left the odd couple of Danny and Kris. It was really kind of hilarious, and I'm sad that they won't be able to do it again this season (unless they do it tomorrow during the results show), because it was a lot of fun.
