Count Five (sometimes known as Count V) was a garage band from San Jose, California. The band consisted of Kenn Ellner, John Byrne, Roy Chaney, John Michalski and Craig Atkinson. The band then shifted genres to mostly garage style rock and roll with influences from The Yardbirds, The Beatles, The Who, and The Rolling Stones.
Their song, Psychotic Reaction, reached #5 on the Billboard Hot 100 charts in 1966, and was selected as one of the “500 Most Influential Songs in Rock n’ Roll History” by the Rock n’ Roll Hall of Fame. Psychotic Reaction was released worldwide and gained popularity in the United Kingdom, Spain, Japan, and Mexico. Psychotic Reaction was popular in the Vietnam War era, and appears in the game Battlefield Vietnam. The song was modeled after the Yardbirds’s song “I’m a Man”, with a repetitious rhythm that eventually changes to a faster beat, an electric guitar playing a hypnotic melody going up the scales, and a similar style of percussion to that of the Yardbirds hit.

I’d never heard of Count Five or Psychotic Reaction, but this is an era & music I love so I YouTubed it. I’ll play some more tonight to make cooking dinner a bit more lively 🙂
I had never heard of them either, but I’m really enjoying finding albums with no real idea of what to expect without listening or looking it up! You’re right, it was such a great era for music!!
