Kim Mitchell is definitely that someone that is worth checking out. He is great. In particular his stuff with the much underrated band
Max Webster.
They made about
7 records 1975-1980 and were one of the best bands around. Being Canadian and on the same label as Rush meant they were always playing in their shadow. Unfortunately they never made in big in the states and folded in the early eighties.
Kim went on to have more success as a solo artist with hits like "Go for a Soda" and "Patio Lanterns" but the really kickin' stuff was with Max Webster.
They kind of sound like Rush meets Frank Zappa if you have never heard them check them out.
