UPDATE: My review here
FYI, the Linkin Park new album "Minutes to Midnight" has "dropped", go cop that!
First impression, it's quality. The style of music/beats is different from that of the 1st two albums. I would compare Linkin Park to The Roots, who can switch their subgenre of music & still produce a quality album every time. The songs here are mellower, without many spastic moments as on their prior albums. However, LP still merges both "hard" sounds with "soft" sounds here, which has been their trademark unique approach since their 1st album "Hybrid Theory".
Here's a video for their single "What I've Done"
