9. The Moody Blues
The Moody Blues have been touring and recording for over 50 years. Songs like "Nights in White Satin," "Tuesday Afternoon" and "Go Now" have been in rotation on classic rock radio for decades, and nobody questions the crucial contributions they made to progressive rock back in the 1960s. These guys were at it years before even King Crimson. Somehow or another, they just never won a ton of critical respect. In 2000, they called a live album Hall of Fame, perhaps thinking hoping they'd soon enter the actual one. It's 15 years later and they're still waiting, but if they hold out long enough they'll probably make it.
