I'm pretty sure I first became aware of him when Sons of Apollo came out, but I didn't know who he was and stupidly conflated Ron Tahl with Kim Thayil (not knowing a thing about either of them and wondering why the Thayil dude had adopted such a stupid nickname...) [/confession of stupidity]
That said, man, what a monster player and seems in the interview to be a really smart but personable guy. I have given the album a listen and found it to be strangely listenable - a feat for instrumental rock music in my book.
