This looks like a great double-bill, happening this Friday, July 16 at Middle East upstairs. I first heard Ha Ha Tonka from their live sessions on the most excellent HearYa blog. I later saw them play at the most excellent Bloodshot BBQ at Middle East last summer. They are most excellent. You should go see them!
The Riverfront Music Festival is a free outdoor concert happening this Saturday, July 10, 2010. The lineup this year looks very good with The Candles (1pm), Sarah Harmer (2pm), Steven Kellog & the Sixers (3:30pm) and The Lemonheads (5pm). I'm most looking forward to The Candles and The Lemonheads, who are currently touring together.
Unfortunately we can't be in two places at once, since the Showcase Fest at Prescott Park is going on at the same time up the road in Portsmouth, NH. That show includes Jon Nolan, Adam Ezra Group, Jason Spooner and Gypsy Tailwind.
