Podbop has rolled out with a new way of bringing music to you. They have a list of artists on tour with mostly full length samples of what they sound like. You can also see who is coming into your town and grab a free track or two before you decide to go to the show. Whether you are looking for local stuff or nationally known artists, you can find your way with other sources I’ve found, some good for the local Tucson music scene and others that are great for all the states.
