I made mention a few weeks ago about a conversation I had with a few people at LL offering a simple idea to address this growing problem. As you look at the "Live Music" listings, it is a jumble of Live music, DJ events, Track Singers, Tribute concerts etc. If you feel like going to a clubbing event with a kick ass DJ, then we shouldn't have to try to weed through 50 others that have nothing to do with what we're looking for. If we want to go see a live performance, where the artist is playing live and singing live, the same applies... same with track Singers, Tribute concerts, and so on.
The idea I proposed to Linden Lab is very simply to add a few levels of categorization. So under a top level Event header of say "Music", there can be a drop down for each category, Live Music, Track Singers, DJ Events, etc.
This will help in a few ways. First and most obvious is that it makes it easier to find what you're looking for.
Second, it makes it better for those who are putting on the events. With the new system, their events will be more highly visible and in the Category they need to be in.
Third, there's no reason a live performer should have to compete for a time slot and advertising space with a DJ event. They are two different genres of music/event.
In my opinion, implementing these minor changes (as they don't require a ton of code or hours and hours of programming) can make a HUGE difference in the overall Second Life experience, especially for new users who may not be entirely familiar with SL to begin with.
