Query: 311...really 4.5 out of 5

this new cd from 311 is not perfect but is worth the 4.5 stars i gave it. The reason is because the way the two singers blend together in harmony is perfect. When you first listen to dont tread on me(the song), it more rock then turns into a little bit of reggae then when the other singer (sa) comes in it just makes the song so incredible. And taht works on throughtout the cd... overall good but not the old 311 we all know. Favortite Tracks Frolic Room, Dont Tread On Me, Whiskey And Whine, Speak Easy, Solar Flare
