OK, pretty lame compared to all the great festivals in this subforum, but Bassnectar is headlining, the venue is great, the weather should be amazing, and it's $32. At the very least, it's an excuse for some of the Phoenix people to get out of the heat.
The lineup is pretty bizarre...it's a bunch of hip-hop acts with some EDM DJs sprinkled throughout.
I'm guessing this will be just a one stage deal...it's a pretty small venue. Probably DJs spinning on the side while the main acts set up. Website says something about "All Day All Night festivities", but I'm pretty sure they have a midnight noise curfew. The venue seems isolated, but there are residential areas behind it, and it's actually right next to a military recreation area. Here's a pic of the venue...
There is a fairly large, flat, open area in front of the stage with a cement floor. Behind this is 10-15 rows of seats, and then lawn behind that. The open area and seats are covered with an awning. Total capacity is about 3000. Sound quality is usually pretty good no matter where you are, but I don't know how it will handle heavy bass. (I've only seen rock acts.) In the picture, there is a fence behind the seats, but this will be all general admission.
You can camp onsite ($25 per Car/Tent...up to 4 people), or there are a bunch of hotels about 2 miles away...anything on Woodland Village Blvd (Sleep Inn, Motel 6, Ramada, Days Inn) or Beulah Blvd (Flagstaff Suites, Hampton Inn, La Quinta, Comfort Inn) is close..also the Fairfield Inn on Milton Rd, or the Hilton Garden Inn on Forest Meadows. For a "fancy" place, the Radisson Woodlands Hotel isn't that much further, and has special rates if you go through the Pine Mountain Amphitheatre website.
This lineup really isn't my style, but I know Bassnectar will be cool, and it's on my birthday, so I'm there. I'm just plugging this because I like to support anything in Flagstaff that's not a Jam Band or Folk/Bluegrass, and I know there are a lot of Bassnectar fans around here. The more people that show up to stuff like this, the more chance we'll have an alternative to 6 Dark Star Orchestra shows every year.
