Gloria Molina Grand Park is such a nice, clean place for free music events during summer time. I have been here particularly for Sunday Sessions. Conveniently located near a metro Red Line. You can enjoy a good picnic with friends. Dance to your heart's desire without being judged (come on, it's Los Angeles--everyone is semi-weird in his own way in this town!). Gloria Molina Grand Park is also pet-friendly. Just watch after them. Not everyone are pet-lovers.
