Best summer festival lineups?

Forums:

I'm planning a vacation with family to either San Francisco, Colorado or New York City this Spring or early summer. What are your favorite festivals or events in these states? I want to get opinions on the lineups for Lok'n/Bonnaroo/etc.

 

Thanks

Are late night Disco Biscuit shows a plus or minus for you?  Do you enjoy smurfy jamgrass?  An eclectic mix of bands or a more homogenized scene?

Delfest (Memorial Day w/e) has a nice lineup for the 10th anniversary at the Cumberland County Fairgrounds, including TAB and Mule. Not your typical jam band fest but it has a lot to offer and family friendly. Line up was just announced this week. I'm also looking to see what Peach has this year (August) as I opted out of Lockn and went Peach last year...planning same in 2017 (Lockn got too expensive).

Free fest in the park first weekend of October. 

I wouldn't pay much attention to the line-ups. Nobody goes for the music anymore. Make your choice based the variety of kind microbrews and farm-to-table food trucks. After you finish your fruity saison and korean-mexican infused tacos, head over to the corporate sponsored wi-fi tent to share pointed opinions with your social stream. Give the beer a 7 out of 10 but offer a slightly less enthused opinion on the tacos, due to the unbalanced spiciness of the kimchi.
