Faith No More first had a top-100 single on Billboard's year-end chart in 1990.
The song was “Epic,” the band's breakthrough single from the 1989 album The Real Thing. On Billboard's year-end Hot 100 for 1990, “Epic” ranked No. 75. It also became a major weekly-chart hit, reaching No. 9 on the Billboard Hot 100.
“Epic” stood out for combining heavy metal and hard rock with funk, hip-hop-influenced vocals, piano, and an unusual music video. Mike Patton wrote the lyrics after joining Faith No More, and the song helped turn the band into an international act.
Readers sometimes confuse a weekly peak with a year-end ranking. “Epic” peaked at No. 9 on the weekly Hot 100, but the question asks when the band first appeared in Billboard's annual top 100, making 1990 the relevant year. Later Faith No More singles did not precede it on that year-end list.
