If you are a music fan and you haven't checked out Pandora yet, go. Now. The site is a product of the Music Genome Project, an effort to analyze all musical styles and create a taxonomy--a genetic code--of hundreds of musical attributes. It's one of the best things out there.
Now Pandora has started a podcast series and a blog that discuss in detail some of the basic elements that make up the music we listen to, such as "Guitar effects" and "Drums and Drumming." Each podcast is about eight minutes long. Subscrbe here.
The thing is... boy, it's refreshing to see a company understand what is all about, isn't it? Pandora has it down cold. The blog and the podcasts are great extensions of their overall mission.
