If you only play bass as well as I unfortunately do, there are easier ways of making a room full of 'fans' puke after your solo. But then again, any kind of purported 'rock' music that would even feature bass solos at all would likely be puke-inducing to my own sensibilities ("My Generation" excepted).
(BTW, does anybody think there is a grosser thread than this in all of the archives? :-)
