I've been a huge X fan from their first album, as if you didn't know from my handle here. I'm really more of a guitar player, so I naturally gravitated towards Billy Zoom's guitar, and he was so damn cool. As I relisten to their music nowadays (and all music now, I suppose) from the perspective of someone who's interested in bass, I think John was a very solid bassist, and he is also a vocalist, songwriter, and guitar player outside of X. His playing is certainly more "meat and potatoes" rather than virtuosic, but isn't that a big part of the bass role? Especially in this genre. I dig him, dig his playing, and always loved his bass...that's some legit relicing. Here they are in 2017. Take a listen.
