What selections do you play when showing off your system to others?
I find that when I'm having someone listen to my system that I usually play the same 4 or 5 selections. I tend to lean towards vocals and acoustic presentations. Mine are as follows:
Hold That Line- Tedeschi Trucks Band
Roadhouse and Automobiles- Chris Jones
The Hunter- Jennifer Warnes
River Blues- Eric Bibb
Flight of the Hippo- Bela Fleck and the Flecktones
It's All in the Game- Merle Haggard
Your Bright Baby Blues- Jackson Browne
What are yours?
