In case you missed these posts, let me mention them again. I am working on making an indexed page where they can reside. Oddly enough the post on the Maxon tube screamer is the most visited of all our posts.

There is an excellent article over at Build !nternet outlining current trends in Myspace design. Definitely read this if you have a myspace profile for your band!
Once you’ve finished reading the article don’t miss out on the discussion beneath. I have personally been coming to the same conclusion recently that a band should have their own .com as well as a myspace. It’s definitely something to consider since with your own website you are freed up to do a lot more with your online presence. In addition, and this is the thing I am really liking about having my own band website, I can see stats of who is visiting and downloading music.
Here is the article:
