While the rest of the country fades into chillier temps, San Francisco's summer is just getting started. With vibes as warm as the summer air, October is perfect timing for Hardly Strictly Bluegrass Festival, as o ver 700,000 poured into Golden Gate Park for a spirited weekend of folk, funk, rock, pop and good ole' Americana. Ninety of music's finest musicians, like Lucinda Williams, John Prine, Randy Newman, Conor Oberst, Black Keys frontman Dan Auerbach, Big Freedia, Emmylou Harris, T Bone Burnett, Laurie Lewis, Buddy Miller, Moonalice and Gillian Welch, played across seven bluegrass-themed stages. Lovely tributes to recently deceased rocker Tom Petty and soul legend Charles Bradley rang out all weekend long.

San Francisco philanthropist Warren Hellman had the right idea when he founded the festival 16 years ago. Free to the public and free of corporate sponsorship, the Hardly Strictly magic lies in its inclusivity. Whether you're looking to chill in San Francisco's luscious Golden Gate Park, picnic on the grass with the little ones or take in some solid tunes, the festival has it all.
