I've been here twice, for Sufjan Stevens and the EVMCO Christmas Concert. I was impressed both times. This is a beautiful venue, like a smaller and nicer Gammage. It is still large enough to be epic, and the acoustics are stellar. Parking in the area isn't awful, though finding your entry door can be a bit stressful.
Still, this is one of my favorite big venues in the valley, and a big reason why Downtown Mesa is a thing now.
