The United States of America, as well as coming up with what must be, in retrospect, one of the least Google-able band names ever, are probably best known today for their self-titled debut album, which was clearly a building block for the Broadcast sound.
Of some marginal interest, then, both to Broadcast fans and to historians of the late sixties (and in particular the narrow, sometimes one-raised-eyebrow quizzical and sometimes (not always intentionally) comedic intersection between the New Yorker magazine and the long-hairs) is this extract from the issue dated 30 March 1968, where one of the mainstays of the magazine, Lillian Ross, writes about going to see The United States of America, an "Electronic Rock Band", perform at Judson Hall.
You're welcome.
