I report, you decide. Even though TSDFN's hit "Sharting in the Holy Water" was one of my favorite songs of all-time, I'm going with Kansas.
"You ain't a rapper because you got a myspace page!" -some dude on the White Rapper Show on vh1 dissing John Brown.
The only two I've heard of are Alabama and Kansas; surprised the other one exist(ed). To me, Kansas only has one good song, while Alabama has a whole greatest hits worth noting. Alabama is my pick.
im suprised someone else has heard of idaho. if you are into the slow-core a'la red house painters, codeine or low than check out their early stuff. they used these cool custom made slack key 4 string guitars w/ odd tunings and tons of controlled feedback. in a way they remind me of neil young and crazy horse, but played at half speed. good stuff, but listening for more than an hour will make you want to slit your wrists.
