It's definitely weak compared to what I remember from the original Music Midtowns. 2005, the last "real" Music Midtown, was $75 for 3 days, 5 stages, and music from 11 AM - 12 AM. This is $100 for 2 stages and 2 evenings (4:30 PM - 11 PM). Not a deal at all when you think about it that way.
"More TBA" makes me feel better about it. The lineup so far just seems a bit weak to me. I was counting on going to it this year but so far nothing stands out for me. :( [I couldn't make it last year.]
