Punk rock in 90s, 00s, and 10s, so pretty much any band that I loved in the 90s that is still putting out relevant music today. Some more recent albums from bands that are my favorites:
Bad Religion - Age of Unreason / True North
Alkaline Trio - This Addiction
Sum 41 - Screaming Bloody Murder
Anti-Flag - American Fall
Pennywise - All or Nothing
NOFX - Self Entitled
Matt Skiba - Babylon
The Songs of Tony Sly: A Tribute
Probably not everybody's cup of tea, but I've always thought that people missing out on Bad Religion/Greg Graffin were really doing themselves a disservice. However, I do realize that music provides different things for different people (love, politics, feeling, being cool, jesus, whatever).
