With video, photos, and live rock songs from the era, some of which are rarely performed in this day and age, this show recreates the era of the mid- to late-1960s, focusing on the music and events leading up to the 1967 Summer of Love. The fact that three of the five members of the band lived through that period as teenagers lends verisimilitude to the event, as does the group’s authentic garage-band sound. And remember: If it’s too loud, you’re too young.
