Geddy Lee is a founding member of Rush. Rush's brand of complex, science-fiction themed heavy metal has been shaping great minds since 1968. Rush is what future software-engineers, architects, and mathematicians listened to while they played Dungeons & Dragons in their parent's basements in the 1970's. Lee's hair -- pictured below in a powerful mullet configuration -- speaks for itself.
The largest audience to ever attend a Rush concert was 60,000 in São Paulo, Brazil. People in South and Central America sure love heavy metal.
