As noted above, that's J. Ahola. He doesn't really do much. Northern Kings with Marco et al, and local Finnish stuff.
I think the guy who did Die Young was also awesome. Really, they were all good. It was a great night
You will find if you search around that almost every singer/guitarist who played has done, or currently does, something local with the main guitar player Erkka Korhonen, who put the whole gig together.
