Author Existence Failure: The sad passing of Allen Lanier in August 2013, the first band member to be offered a personal opportunity not to fear the Reaper. Largely averted, as apart from one-off appearances, he had already retired from the group owing to the illness that later killed him.
DFTR (Don't Fear The Reaper) was appended to so many obituaries that the acronym appears to have become an instant meme, a contemporary alternative to RIP.
Black Sheep Hit: "Don't Fear the Reaper", which is a lot softer and more melodic than their usual style.
All of the group's major radio hits - "Don't Fear the Reaper", "Burnin' For You", and "Godzilla" - were sung by Buck Dharma rather than regular lead singer Eric Bloom. One who picks up their albums after being introduced to them on the radio might be quite confused as to who this other singer is.
Development Hell: Sandy Pearlman wrote the bulk of Imaginos before he even met the future members of BOC. It was initially to be released immediately after Secret Treaties, but it kept getting pushed back due to Creative Differences. After Albert Bouchard quit the band in 1982, he recorded it himself with the intent of releasing it as a solo album, but CBS Records balked and insisted it be billed as a BOC album - leaving it in limbo for another six years until it was released with vocal overdubs from Buck and Eric and a massive number of session musicians billed as "The Guitar Orchestra of the State of Imaginos" - including two songs with lead vocals by non-members - one, the title track, featuring songwriter Jon Rogers, and another by Joe Cerisano, a session vocalist best known for recording KFC jingles and singing lead on "Hands Across America". And on top of all that, the published album had the tracks out of order.
Executive Meddling: The reason Imaginos was released in abridged format (the band wanted to release at least two CDs' worth of material) and out of order. The internal chronology of the tracks is not exactly clear, but one suggestion is:
1. Les Invisibles
3. Del Rio's Song
4. Blue Öyster Cult
6. I Am the One You Warned Me Of
7. In the Presence of Another World
8. The Siege and Investiture of Baron von Frankenstein's Castle at Weisseria
9. Magna of Illusion
Fan Nickname: Fans started to refer to the band as "Two Oyster Cult" when Bloom and Roeser were the only original members left in the band. Sardonic British rock journo Tony Tyler witnessed the band's Five Guitars setpiece during a London gig. Writing for the NME, he contrasted the size of the guitars against the generally medium height of the band members and labelled them the Five Dwarves Of Heavy Metal.
Hey, It's That Guy!: The video and single from their Extraterrestrial Live album was a cover of The Doors' "Roadhouse Blues", recorded with Doors guitarist Robbie Krieger.
"When the War Comes", on Club Ninja, featured a spoken-word intro by a then-relatively-unknown New York DJ named Howard Stern.
Stern is credited with co-writing the song.
The group's current bassist Rudy Sarzo previously played in a slew of other metal groups, including Quiet Riot, Whitesnake, and Dio. The group often pays homage to this by including an instrumental medley of those bands' songs in the middle of "Godzilla".
Promoted Fanboy: In 1974, John Shirley wrote the novel "Transmaniacon", deriving its title from a song on BOC's debut album. 20 years later, the band recruited him as their principal lyricist for "Heaven Forbid" and "Curse of the Forbidden Mirror".
The entire band counts as this, being fans of Michael Moorcock — and then collaborating with him on an album.
