This Deep Dive from Kenny Denton’s memoir recounts a chaotic attempt to record the band Chicago at the 1970 Isle of Wight Festival. Tensions rose within the mobile recording truck as conflicting instructions from the band's own production team created a disorderly and ego-driven environment. The situation escalated into total pandemonium when the recording equipment suddenly lost power, plunging the crew into darkness mid-performance. While the visiting engineers panicked, the local staff eventually discovered that the failure was caused by a dislodged power plug. Although technical operations eventually resumed, the author notes that the hostile atmosphere persisted for the remainder of the concert. Over-preparation by the American team ultimately proved no match for a simple, accidental physical mishap.
