…turns out they’re alright. This may come as a shock, but there’s a festival in town this weekend: installment number 4, if my math is correct, of The Kids Are Alright Festival, held at the Bob Bullock State History Museum. It’s what we call a U21 festival. Prices are exceedingly friendly – free for events on Friday and $6 for a wide array of music on three stages Saturday. (Above is Sienna of the group Schmillion, winners of the Chronicle’s 2009 ‘Best U18 Band’ poll…) The kids, it turns out, are not just alright, they’re total pros.
