Deep Purple

Are legendary English rock pioneers, famous for defining hard rock and heavy metal with their blend of blues, classical, and psychedelic music, featuring iconic guitar riffs (like "Smoke on the Water"), virtuosic solos, and frequent lineup changes, especially the classic "Mark II" era. Alongside Led Zeppelin and Black Sabbath, they formed the "unholy trinity" of early 70s British rock, selling over 100 million albums and influencing countless bands.
