"ROLE Magazine is a monthly publication dedicated to highlighting the many facets of Second Life™ and to showcase the most interesting people, places and things in a high quality magazine production." Just stumbled across this while looking for educational areas - interesting publication.

This is a great looking area found in Second Life that teaches visitors about the different periods in music history. Each music era is housed in a building representative of the time period. They also hold online interviews with various artists/scholars in Second Life via vodcasts. Although there is a teleport link on the site I couldn't get to the academy. The site says that you can IM the director once you have an avatar and hopefully he can provide access.

Live music performances from Classical to Heavy Metal! A great venue for people to attend concerts that they may not be able to get to in the real world! One education site had their students watch a live performance and write a critique. Visit this site to see the concert schedule: http://musicisland.ning.com/

This is a wiki that explores educational uses of different virtual learning environments. It was really interesting learning about programs/tools other than SL, such as augmented reality. Click on the "About Us" link to find out more about the Horizon Project.
