Otter asks: "iTunes comes with a sampler of MP3s selected to appeal to the Apple demographic. The one that really caught my attention was a track by Sasha and John Digweed, which has inspired me to learn a bit about electronic music. Unfortunately, I don't know anyone who likes that stuff and my local Tower Records only has Moby (didn't like it),Paul Oakenfold (not bad) and 11,000 'Best of Ibiza' sets. What are the must-haves I should start with? What are the best online communities and places to learn about new artists? Feel free to define 'electronic' as broadly as seems appropriate." I used to shop at Homebass, but they just went out of business, which is sad, as they had one of the most comprehensive selection of electronica that I have ever seen, and most of their tracks had MP3 previews. If you were going to try and turn a friend on to Electronica, what artists, songs, or even specific mixed sets would you suggest? What online sources of electronica are still around.
