In 1969, rock concerts at large indoor venues, such as the Forum, were relatively new. It was also a time of social unrest and popular concert events attracted their share of difficulties. Hendrix biographer Keith Shadwick commented, "As so often there was a troubled atmosphere in the arena reflecting the turmoil that continued to dominate America's social and political life; here it was exacerbated by the security personnel's reaction to provocation from unruly elements in the crowd." In an effort to prevent the capacity crowd from rushing the stage, "the cops had lined up on the stage in front of him [Hendrix], in some mysterious police method of crowd control". Tensions heightened and those in charge threatened to cut the power; Hendrix announced "Look, they're going to cut the show short if this keeps up. So just sit down and be cool so these other 'people' [coughs] will get off the stage." During his performance of "
Purple Haze", he changed scuse me while I kiss the sky" to scuse me while I kiss that policeman". Some see his attempts as sarcasm, however, Shadwick feels that with humor and common sense, Hendrix "repeatedly defuses a situation where more heavy-handed methods would only make things worse". Also, by 1969, difficulties between Experience bassist
Noel Redding and Hendrix were coming to a head. Hendrix had played bass on several songs that appeared on
Axis: Bold As Love (1967 and
Electric Ladyland (1968), and invited other musicians to record on the latter. In his autobiography, Redding expressed his increasing frustration with Hendrix's habit of showing up late for recording sessions, sometimes accompanied by a group of hangers-on, and generally not being supportive of his role in the group. Redding responded in part by forming his own band,
Fat Mattress, where he returned to playing guitar, instead of bass. During the Forum concert, Redding's approach to dealing with the security issue also showed the growing division, with his angry comments at odds with Hendrix's more conciliatory approach. After riots during performances in San Diego (May 24) and Denver (June 29), Redding quit the Experience and returned to England. ==Critical reception==
