Czech rock group. Founded 1974 in Plzen (former Czechoslovakia) by Oldrich Riha and Jiri Sindelar, initially named “Mahagon”. After being banned by the regional communist authorities they relocated to Prague. Renamed on Mahagon’s request to “Katapult” in August 1975. They became one of the most popular Czechoslovak live acts of the late 1970s, releasing two best-selling albums and several SPs, winning the “best group” category of the popular youth magazine Mlady svet’s annual reader award “Zlaty slavik” (“Golden Nightingale”) in 1979 and 1980. Despite further bans by the authorities during the late 1970s (eventually they were not allowed to perform in Prague at all) and particularly in the first half of the 1980s (no recording permission despite valid Supraphon contract, absolutely no radio or TV presence), the duo Riha/Sidelar remained continuously active as “Katapult” with changing (or returning) drummers until Sindelar’s premature death in January 2009.
