Although the Album starts off in a very poppy direction, it finishes with an old-school feeling blues masterpiece. It is almost as if the whole album shows John's switch from the old "pop" to the new "blues/rock".
Overall, The Album is a very enjoyable experience. Although it definitely isn't the #1 album on my shelf, I still hold it in high regard. In the future I see Mayer fusing many new styles into mainstream music, and this blues/rock album is just the instigator.
Gorillaz is a super classic band, and for a good reason. With some of the best combinations of electronic music, featuring artists from Mos Def, to MF Doom, it's a really incredible band.
Their newest album, "The Fall", was even recording entirely on an iPad! I highly recommend they become an integral part to your music library, and I've been listening to them for the last month straight (Religiously).
