The California Academy of Sciences' biggest bash is back! On April 27th, join us for the Big Bang Party After Dark with headliner Hot Chip. Enjoy live music, late-night bites, and craft cocktails at multiple open bars—all inside the greenest museum on the planet. And if that's not enough, don't miss the Silent Disco in the aquarium where HUSHconcerts will be spinning hip-hop and pop favorites under water! Be sure to also experience the cool new psychedelic cocktail lounge in celebration of the 50th anniversary of the Summer of Love in Golden Gate Park.

Four lucky 7x7 readers will win tickets to this annual fundraiser; proceeds support the Academy's world-class science education programs. All you have to do is sign up for our daily newsletter below, and we'll share your info with the Academy for your chance to win.
