Astrid Kircherr was out with some friends in her native Hamburg one night in 1960 when they stepped into the Kaiserkeller and came face to face with rock n’ roll personified. In the next four years Kircherr documented the transformation of the original line-up of the Beatles from five to the Fab Four, from cherub-faced rockabilly youth to the centerpiece of probably the most viral explosion of global youth culture ever seen. The pictures she took in those days — before the Beatles were the Beatles — might as well be from a different world. In a way they are from a different world, though one whose orbit paralleled ours before “She Loves You” awakened some dormant spirit in the teenage mass and a new course put some drift between us. The Early Beatles Collection, including rarely seen photos taken by Kircherr between 1960-1964, opened today at the Leica Gallery Los Angeles and is up for a bit, stop by if you’re in the neighborhood.
