The first set was an early afternoon acoustic performance (announced as a "stripped-down set") played in the Grassroots Stage. It seemed that not a lot of people were aware of this set, but even though the crowd wasn't that big it was very enthusiastic. The band was very tight and the song selection was perfect for an acoustic set.
The second set started at 9:00 PM and was played in the main stage, which means that this time around the crowd was huge. This set was as different from the first as they could be - a lot of jamming and songs that segued into each other seamlessly. It was probably the most jamming set I've ever seen moe. play.
Overall, this was a great day and I'm so glad that it's already available for download. A special thanks to whomever decided to include the acoustic set in this download!
