The colors and graphic are very engaging. Though the text gets lost. The date needs to be a thicker font. Possibly create a text lockup. That will help it sit better on the background. The band names, that will take a little more finesse. Placing a stroke on all text is a tad too much. The simple white outlined box in the lower left works quite well. Look at that system as a possible option.

yeah, thicker font should be used on it, I'll keep that in mind when designing such a colorful artwork ;)
