The answer, another visit from my friend, John H. You met him through the most recent Space Shuttle and Ocala National Forest Tales. I met him in first grade. He drove over from St. Pete to kayak and see some friends perform at a local establishment. Or the other way around. Anyway, I worked to noon, John got stuck in traffic, so it was almost 3 PM when we arrived at Katie's Landing on the Wekiva River.
The second act, Hymn for Her, a duo from Philly. The sound they made from the cigar box, and acoustic, harmonica, and minimal drum kit was amazing. Here's a taste.
The third group, or duo, and second we saw, were the folks John came over from St. Pete to see. Purgatory Hill. Pat MacDonald and Melanie Jane.
