Rise Against - Appeal to Reason
AWOLNATION - Megalithic Symphony
The Black Keys - El Camino
Skee-lo - I Wish
Semisonic - Feeling Strangely Fine
I really like Rise Against's take on accessible melodic hardcore (even if melodic hardcore is pretty accessible by default)
I can't seem to find anything like RA that has the same kind of feeling around it. Tim's vocals are incredible; I don't usually like screaming but he does it perfectly, and everything else he sings is wonderful as well of course. He's also got some great lyrics, and they're all very good musicians.
