I always let guests have the the first picks, the start working my faves into the mix. Usually I'll suggest Eva Cassidy, Aaron Neville, if it's Jazz, Charlie Haden and Pat Metheny "Beyond The Missouri Sky", Diana Krall. Eric Clapton and BB King "Riding with the King", Carlos Santana "Europa", Stevie Ray Vaughan "Texas Flood".
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?
