If you want to find where your favorite band or artist is playing you could do worse than search Music Enthusiast. Music Enthusiast searches Eventful for upcoming concerts and plots the results on a Google Map.
To view the scheduled concerts of a band or artist you just need to enter their name. Music Enthusiast then searches Eventful and adds a map marker for each concert date it finds. It even plots the concerts in chronological order. The green marker shows the first concert on the tour and the red marker shows you the location of the tour's finale.
Music Enthusiast also searches YouTube for you. So once you have finished searching for concerts you can click on a YouTube thumbnail and watch a video of your favorite band.
