In 1971, Blue Oyster Cult presented a new LP, Tyranny and Mutation. It was recorded while the musicians were touring the world in support of the previous album. The LP featured such successful songs as "The Red and The Black", "Baby Ice Dog,” and "Hot Rails To Hell". It climbed to the 122nd spot of Billboard 200.
In 1974, musicians presented the third album, Secret Treaties. It earned numerous positive reviews from the critics and came in 53rd on Billboard 200. The album featured such hits as "Astronomy", "Career of Evil", and "Dominance and Submission". It earned a gold status from RIAA. At that time, many fans started trying to book Blue Oyster Cult for private events.
In 1976, the band presented its first live album, On Your Feet or on Your Knees, which became gold. Two years later, they recorded Agents of Fortune. The album quickly turned platinum. It featured a hit single "Don’t Fear the Reaper", which climbed to the 12th spot of Billboard Hot 100. The album also became popular in Sweden, Canada, and the UK.
In 1978, musicians recorded a new live album, Some Enchanted Evening. It reached the 44th spot on Billboard 200 and became platinum in the USA.
During the supporting tour for the new LP, Fire of Unknown Origin, Albert Bouchard left the band. For some time, musicians weren’t giving any concerts. They spent the next several years doing studio work.
In 1983, Blue Oyster Cult presented The Revolution by Night, which featured a hit single "Shooting Shark”. After the release, the artists asked Bouchard to rejoin the band. The drummer’s return led to numerous disagreements so the group stopped performing once again.
In 1987, the artists came back to the stage when they got an invitation to perform in Greece.
At the end of the 1990s, Blue Oyster Cult signed a contract with CMC Records and recorded two new albums, Heaven Forbid (1998) and Curse of the Hidden Mirror (2001). They didn’t get into any of the popular charts.
At the beginning of 2007, the band presented an extended version of the albums, Spectres and Some Enchanted Evening. In 2012, their songs became a part of a 17-disc collection called The Complete Columbia Albums Collection.
Even though the artists haven’t recorded any new studio albums since 2001, they have been touring the world with old hits. Blue Oyster Cult participates in music festivals and performs at private events.
