Here's the idea: feature any artist you love, especially those you think deserve more attention (though that's not a requirement--anyone is fair game!).
Give the artist/band, their genre(s), and three songs that give a good introduction/overview to their sound and style. Think appetizer, entree, and dessert. (Or just three appetizers--it's good to get us wanting more!)
Include a brief description of the artist and each of the tracks. Include any other information you feel is relevant.
Feel free to feature more than one band/artist, but in the interest of organization, make each its own separate top-level comment.
(See my example comment below to get a better idea of what I'm going for.)
