Bands I discovered or just finally paid attention and got around listening to (and liking) this year:
Against Me!
The Moldy Peaches
Mclusky
Minor Threat
Opeth
The Gathering
Within Temptation
Jack Off Jill
Joy Division
I'd say that The Moldy Peaches and Against Me! are my best finds by far, with Mclusky coming a close second with Minor Threat......
But yeah, Against Me! and Moldy Peaches are just two very different original bands thatstand out, and I love them immensely, they are probably in my top 20 all-time favourite bands!
