Pink Floyd

Pink Floyd is a widely acclaimed psychedelic rock band which originated in England in the 1960s, and achieved international success with a series of albums characterized by conceptual themes, sound effects, and oftentimes a somewhat dark tone.

Pink Floyd's most successful albums include "The Wall," an allegory about a boy losing his father in the Second World War, "Wish You Were Here," and " The Dark Side of the Moon." "Dark Side" has spent the most amount of time on the "Billboard Top 200" chart of any album in history, although not contiguously.
