Joy Division, with an important Transmission.
This might be the best one-song TV performance I’ve ever seen, and it’s 40 years old now. I’m having trouble nailing down the date, but there’s a graphic for Unknown Pleasures behind them; that album was recorded in April of 1979, and behind it they played twice on British television: in July of 79, on Granada TV, and soon after that on BBC2’s Something Else.
They’d release Transmission as a stand-alone, non-album single the following November, seemingly poised for larger success. And then, of course, Ian Curtis would take his own life in May of the following year, at 23.
