now that I'm at a computer I looked it up. It was their "backup vocalist/guitarist" that quit the band. All the news titles were pretty deceiving in that they all just led with "Such Gold Vocalist quits" or whatever, so that's probably where I got the idea from. Glad that it's not the case.
I loved when the backup vocalist cut in, and I didn't know he quit, so that sucks. But the focus has always been that lead guitar and Ben (I believe that's his name) aggressive tone so I'll live.
