McCarthy, Harris and Gooday founded Nitzer Ebb in 1982 and held their first musical performance at the Chelmsford
YMCA. They opened for
Depeche Mode during the European leg of their
Music For The Masses tour and joined the European and North American legs of their
World Violation Tour, further exposing Nitzer Ebb to an international audience. McCarthy was responsible for most of the band's lyrics. His performance style, particularly in the early years of Nitzer Ebb, frequently involved repetitive chants and energetic live performances. Mike Boehm of the
Los Angeles Times described a 1989 Nitzer Ebb performance as an "interesting show, thanks largely to McCarthy's athletic, pumped-up performing style and the punk-influenced fervor of his yowling. With short, tousled hair, angular looks and jerk-to-the-beat movements, he resembled
Mark Mothersbaugh of
Devo, minus Mothersbaugh's way of sweetening technological music with pop hooks." In a review of a 1992 Nitzer Ebb performance,
New York Times journalist
Jon Pareles wrote: "[Nitzer Ebb's] songs rant about hopelessness or explore dark impulses, with chants that are just barely melodic above dank grids of electronic sound," and added, "when Mr. McCarthy sings a melodic line, he dips into a
baritone register that echoes
Jim Morrison. But more than most of Morrison's descendants, he seems immune to pretensions of
Romantic poetry; he stares at brutal, murderous impulses without the buffer of flowery metaphor. And as he rants, he offers catharsis to an audience eager to slam its frustrations away." In a 2018
PopMatters article, Hans Rollman wrote: "To watch one of Nitzer Ebb's early videos—"Murderous", say, or "Join in the Chant"—is to be left breathless at the angry passion and sheer physicality of the energy expressed on the camera. Ironically, McCarthy explains, the frenzied body movements and violent passion expressed by the band, and especially by McCarthy himself, was a reaction against the stage fright he felt when they first began performing. He was only 15 at the time." Subsequent to the band's 1995 album,
Big Hit, Nitzer Ebb disbanded. They reformed in 2006, released two more albums, and continued to tour into the 2024, before McCarthy had to take a break due to health reasons. ==Collaborations and solo work==
