The header on the new website is way too big. I mean, it's just flat-out beastly. Very distracting and, imo, off-putting. A good website in my opinion should be clean and very un-busy to leave room for the content.
Also, MP3s are best in chronological order, or some sort of chronological grouping. It helps the listener to pick other pieces written closely to the timeline of whatever they may have just listened to (speaking from experience, pieces in close proximity tend to have more stylistic similarities than something that was written, say, 6 months prior).
The tables in the equipment section are very 1990's Geocity-esque, which is not a good thing, as far as I'm concerned. Also: having contact info
and a guest book seems somewhat redundant. I'd stick with the contact info, since the latter is equally reminiscent of Geocities.
The drop-down menus are good, though. They save a lot of unnecessary page navigating.
Just my toonie worth of advice.

Haven't designed a website in years, but I know what I like. Go to websites that you like, from an aesthetic standpoint, and see what makes them work so well, and then integrate elements of that into your own webpage.
