Starting out with Jeff Nystrom (bass), Ron Chenier (vocals/guitars), John Chenier (drums) and Ed Eagan (keyboards) the act would debut with Round One (1979) and Hot Spikes (1980); the latter released on major A&M.
The line-up would now feature Ivan Tessier (keyboards) and Bob Patterson (drums) for Fleet Street (1981). But this line-up would change again for In The Red (1983). The line-up would next feature Cliff Davies (ex-Ted Nugent; drums; RIP: April 13, 2008, suicide, age 59) and eventually also include Bob Moffatt (bass), Mike Fenton (bass), Lynn Wells (bass), Andre Gauthier (drums) and Gary Thomas (drums) for Danger Zone (1985), Reign Of Terror (1993), Loud Loud Loud (1995) and Bolted Door (2006).
The band broke up in 1986, and in the intervening years Chenier would occasionally resurrect the band with a new lineup and occasional new albums as well, specifically Bolted Door (2006) featuring himself with Tom Mair (guitars), Nor Reinehc (bass), Laurie Curry (keyboards) and Kevin Radomsky (drums). Chenier has also served as a producer for other bands over the years.
