There are so many bands throughout my lifetime that I've really gotten into and have been unable to figure out why everyone in the world didn't too. Back in '97 I picked up a CD from a band called Star 69 -- their debut and only record, I think -- and I still play the hell out of it to this day.
Great alt-rock-countryish sound. Huge hooks. Gorgeous lead singer. I have no idea why they never caught on.
