One comment about Search Engine Optimizaton (SEO) ...
The best thing you can do for your website and the website of those individuals you are placing a link for (ie. Drummer Cafe) is to use a text link ... like this:
Drummer CafeAn on-line community for drummers & percussionists from around the world; novice to professional.
One of the less effective ways is to only place a banner with a hyper-link, like this:

Using just the banner is great for individuals, but search engines often times don't register it, so the benefit is gone.
If you want to use a banner, such as for the Drummer Cafe, and want us to fully benefit from it, try doing something like this:
 | | Drummer Cafe An on-line community for drummers & percussionists from around the world; novice to professional. |
Notice that in this last example, the logo is linked, but there's also some text linked to the website. The text gets optimized as a text link with the search engine. I understand that this might not be something you want on your website, but as far as being beneficial, it's the way to go.
To be honest, links that only point to the Drummer Cafe and are not reciprocated, are the best for the Drummer Cafe. Search engines such as Google deduct page ranking points when two sites exchange links. If you only link to the Drummer Cafe, it serves us well ... if the Drummer Cafe links back to you, we all lose points and our rankings go down.
