Flowers of Evil is the third album by American hard rock band Mountain, released In 1971. The first part was recorded in the studio and the second during their Fillmore East concert. Both recordings are great and the live recording includes their famous cowbell-tinged song "Mississippi Queen". The two sides are impressive in their own way.
