Alex Chilton (December 28, 1950 – March 17, 2010) first swam into my consciousness in 1967 as the lead singer of the Box Tops, part of the blue-eyed soul singer wave. In the early 70s he was a founding member and lead singer of Big Star, a hugely influential powerpop band that withered without any decent support from their record company but reached cult status over time.
From Wikipedia: Before it broke up, Big Star created a “seminal body of work that never stopped inspiring succeeding generations” in the words of Rolling Stone, as the “quintessential American power pop band” and “one of the most mythic and influential cult acts in all of rock & roll”.
Alex Chilton died at age 59 of a heart attack. He’d experienced symptoms for weeks beforehand but, hey, no health insurance so not doctor visits. Four years later, with the ACA, he might well have survived.
