While the traditional Second Life Birthday celebrations are now pretty much coordinated and run by the community – hence the title Second Life Birthday Community Celebrations, the Lab has a track record of sharing in the celebratory mood around the time of SL’s anniversary through various promotions, gifts, and so on, often as an overall part of the community celebrations.

In 2015, the Lab held an Anniversary Music Festival, for example (and among other events) – and they’re doing the same again in 2016, as Xiola Linden has blogged:

Last year’s auditions turned out to be an incredible showcase of some of the diverse musical talent in Second Life. It was its own mini-musical-fest – with nearly 50 musicians pulling out all the stops in front of the Second Life music community. This bite-sized showcase led to the final line up for Music Fest. It’s definitely worth reading this audition day wrap up from musician and Second Life Resident Zak Claxton on his blog from May of last year.

This year, once again we’re hoping to draw out all you guitarists, bassists, drummers, singers, tambourine shakers and other music makers to come audition for the festival. All genres are welcome! From bands to solo acts, opera to rock and roll – we encourage anyone to sign up for consideration. The Second Life Music Fest is an opportunity to perform at one of the biggest celebrations in Second Life, and it’s a paid gig!
