LOL! You sound just like my dad. He's 56 years old and he pretty much doesn't fancy anything post-1990 either!
For instance, when the last "Rolling Stones" album came out in 2005 ("A Bigger Bang"), I bought it out of curiousity and to be honest, I loved it. Given the fact that my dad loves "The Stones", I thought he'll really enjoy the album. Well, I couldn't have been more wrong! He kept giving me all kinds of lame excuses saying that he is way too busy to actually listen to it and I pretty much gave up in the end! He also told me that he wanted to remember "The Stones" for who they were! My face on hearing his reply looked like this : Hell, I don't think he will even think of checking out that new album by David Gilmour! Even if Led Zeppelin was to produce new material right now, my dad will just say no! He'll probably say "Zep died, when Bonzo died".
I also tried to get him to check out "Radio Moscow" who sound so much like Clapton and Hendrix (my dad's favourite guitarists of all time apart from Jimmy Page of course) and his reply was "Don't get me wrong, I don't want to listen to a kiddie band!". I guess he said that because Radio Moscow consists of members who are 20-somethings!
I, on the other hand, thanks to this forum, last.fm, firmly believe that there are so many amazing bands out there these days. You just have to open your heart, mind and soul and of course do a bit of running around and literally pounce on the new stuff and try your very best to stay away from the radio which is a pretty fucked up indicator of what's actually good these days! When I find amazing new stuff (especially bands in the underground scene which very few people have heard of), I feel this sense of joy and accomplishment knowing full well that I have discovered obscure and underrated gems!
