There are a lot of neat guitar noodlings and vocal harmonies. Pain never rests on their predecessors, however. Bet you can't listen to just one. Pain is really hard to pin down, save for the fact that they have lots of energy and are really tight. The closest band that I can think of is Miami's I Don't Know, who also blend styles and switch gears with ease.
Lyrics are a bit on the silly side.
The band's process of musical maturing seems to be heading in a great direction. The songs are extremely melodic and catchy, utilizing the right mix of horns, crunchy guitars and groovy bass. Really youthful, clear vocals that remind me of the poppiest of ALL songs. This band is definitely different. The lyrics are very silly but not stupid.
