gramatik was pretty sweet, but it was all the same as was on the album. plus, his guitarist isn't all that interesting. granted, it's pretty difficult to really change/jam on your albums so I'll say that they did play really well for what they put out.
but for rills, the opener was this band called caravan palace and they put on a SICK show. super energetic and entertaining in terms of both music, dancing, performing, all that ish. if they hadn't opened, gramatik would probably have been way more impressive to me, but they blew that shit up. highly recommend seeing them if you get the chance. Kinda remind me of beats antique, but not as weird haha..check em out if you get the chance
