Which significant music festival took place in 1967 and is often associated with the counterculture movement?

The Monterey Music Festival, held in 1967, is widely recognized as a pivotal event in the counterculture movement of the 1960s. It showcased a plethora of artists who would become icons of the era, including Jimi Hendrix, Janis Joplin, and The Byrds. The festival served as a celebration of peace, love, and artistic expression, aligning closely with the ideals of the counterculture that rejected mainstream values and promoted alternative lifestyles.

Unlike Woodstock, which took place in 1969 and is often more widely cited in popular culture, Monterey set the stage for the burgeoning psychedelic music scene and was one of the first large-scale music festivals. It also marked a shift in how music festivals were perceived, moving from local events to significant cultural happenings. The festival's eclectic blend of music genres and its emphasis on social and political messages resonated deeply with the sentiments of the time, making it a landmark event in the history of music and social movements.

Other festivals listed, such as Coachella and Lollapalooza, were established later and do not have the same historical ties to the counterculture movement of the 1960s.
