As with Rudy Sarzo, I really didn't know anything about Adrian Vandenberg until I started working on this site. But again, you can't do much reading about Whitesnake without realizing that he was a hugely important part of that band; David Coverdale had wanted to work with him for years before he actually joined, and he was the only member to last though three of the infamous Whitesnake lineup changes. He also had his own band before Whitesnake, called simply Vandenberg, and they apparently had a hit in the US in the early 80's called "Burning Heart." (Though it didn't ring any bells with me when I heard it recently...) Vandenberg is a pretty decent band, though; Adrian did all their songwriting and guitar-playing, so that stuff is top-notch, and their singer, Bert Heerink, sounds like a cross between Dave Bickler (Survivor's first singer; the one who did "Eye Of The Tiger") and Klaus Meine from the Scorpions.
Besides being talented, however, Adrian himself is quite a good-looking fellow, and tall--my goodness, the man's 6'6"! He's Dutch, too, so I expect he must have at least a bit of an accent... unfortunately all the interviews with him that I've found so far were print, not audio. But apart from anything else, I think I've figured out the real reason why I like him: He's like Jareth's younger, ganglier, and less enigmatic brother.
