The Jimi Hendrix Experience
From Memory Alpha, the free Star Trek reference.
The Jimi Hendrix Experience was a 20th century Earth rock and roll trio, lead by guitarist Jimi Hendrix, that was popular during the mid-1960s.
When O'Brien and Kira briefly appeared in 1967, the Hendrix version of the song "Hey Joe" was playing loudly from a nearby van. (DS9: "Past Tense, Part II")
