Re-ac-tor is the eleventh studio album by Canadian musician Neil Young, and his fourth with Crazy Horse, released in 1981. The album married the electric guitar crunch of the late 1970s Crazy Horse sound with early 1980s new wave rhythms. The simplistic, overdriven sound of the songs can be seen as a continuation of the punk-influenced numbers of Rust Never Sleeps such as "Sedan Delivery."
