Through its acceptance by "serious" composers, according to Schaffner, "Sgt. Pepper" satisfied the ambitions of a staid, middle-age American audience keen to be seen as in tune with young people's tastes, and every major rock LP was subsequently given the same level of critical analysis. In 1977, the LP won Best British Album at the inaugural Brit Awards, held by the BPI to celebrate the best British music of the last 25 years as part of Elizabeth II's Silver Jubilee. When EMI issued the Beatles' catalogue on CD in 1987, "Sgt. Pepper" was the only album afforded a dedicated release. EMI marketed it as "the most important record ever released on compact disc".
