Earth Day Free Concert in the Park

It's that time of year again - Earth Day hits SF next sunday, with another rendition of the Green Apple Music Festival. This year, the lineup includes Mickey Hart and, my fave, Brett Dennen. I wish I knew what time he was on, since I'd love to go check him out. There are a couple other bands I don't know, Yonder Mountain String Band and Dan Hicks and The Hot Licks, but I'm sure they're good hippie-dippy music. And hopefully next weekend is as beautiful as this one!
