Temmu is an insane player but he isn't allowed write anything in Wintersun, that's Jari Maenpaa's baby so he's basically just a touring guitarist for them since Jari plays all the guitars on the album. Jari is an equally good player but his compositional skills on recent albums are questionable. Teemu has writing credits for his new band Smackbound and the Imperanon 06 demo. On My Space he had a neo-classical project that was crazy but never went far. I wish I saved some of the songs. Jason Richardson, Stephen Taranto and Rick Graham are some other players with insane skills. There's no shortage of virtuosos now with Instagram and Youtube to show off your chops. Alcohol effects people differently so for guys like Jeff Loomis they were still able to constantly practice and play their songs to a high standard live but for others it changes their life style so they stop practicing and trying to keep their technique up. Then there's how it effects your motor skills and the long term damage it can do from prologued use. Alexi was never the cleanest player when compared to guys like this but it was his compositions that made him stand out so much.
