Have you been using Tunes inSL? If not, why not? My friend Crap Mariner has pulled together a great website and inworld location that makes it super easy to find out about SL musicians and provides links to places where you can buy their music including itunes and CDbaby. I use the Tunes inSL page a lot when I am writing Chestnut's Choices. There simply isn't a better web based resource for information about live music in SL I have found.
Last night Crap sent me a link to the new location of Tunes inSL. The store is decorated in classic Crap-style with rotating gears overhead as you enter.
The walls are covered with information about SL musicians. Album covers play as a slide show under each individual's name, which is a nice touch.
When you click on the artist's name you are offered a link to the Tunes inSL page about that person.
When you click through you will find links to the musician's web page, myspace, group, itunes or wherever you can buy their music. As an aside when I was at the Fierce Tibetan Gods show they other day they mentioned that you can buy their music on xstreet.com, which I did not know. Cool, right?
Note: The Express Hud is still on my screen and for now has officially replaced my Mysti Tool. I also strongly recommend the Emerald Viewer . It is fast, stable and has a lot of great features.
