GP is a bass player. He's also a fan of the bass vituoso Les Claypool, who leads the band Primus. I am a fan of Rush. When I saw that Primus' tour this year is a tribute to Rush and they were playing in Chicago for GP's b-day, it was a done deal.
Primus is not for everyone, but they put on an absolutely amazing show. CP & GP had seats down on the floor in front of the stage. DN & I sat up in a balcony box. Because the music was so bass-centric, no one needed earplugs. It was an amazing show!
The next day, we got GP on his way back to Lincoln via plane, train, and automobile.
