This is a work in progress as I am sure I have missed quite a few bands / musicians but this is the initial list I could think of. Out of nearly three decades I can't say I ever had one bad experience with opening my home to bands. Sometimes only one or a few members of a band would crash at our place sp instead of listing people's individual names, it seemed more logical to list just their band.
I didn't add Yo La Tengo or Silkworm because I lived in their homes (cat sitting) for many weeks rather than them staying with me.
In no particular order:
Treepeople (pre-Built To Spill)
Archers of Loaf
Superconductor (pre New Pornographers / Thrones)
Fitz of Depression
Peechees (members of Bratmobile/Rice)
Red Stars Theory (members of Modest Mouse / 764-HERO / Satisfact / Lync)
Sunn O))))/Engine Kid/Thorr's Hammer
Sunny Day Real Estate
Walk the Plank (Calvin Johnson)
Sons of Ishmael
Some Girls (American Nightmare / Locust / Cold Cave)
