Yeah, but saxophones are used a lot more in jazz, and they don't show up in prog as often as flutes. So it's still kinda weird.
Bass clarinet is kinda cool, just because it's not a regular clarinet. I've played flute since I was ten, picked up sax in junior high, but man, learning clarinet was nuts. It's just a weirdass instrument. I've even played oboe and English horn, though I don't own any. So as someone who's played them all, I think I can safely diss the clarinet.
