Here’s one ESPN’s 30 for 30 series has yet to cover: On June 12, 1970, Pittsburgh Pirates pitcher Dock Ellis threw a no-hitter against the San Diego Padres. It was the 174th no-hitter in Major League Baseball history, but it was the first (and presumably only) no-hitter achieved by a player who says he was under the influence of LSD at the time. The 70s, man.

Ellis’s incredible claim gets the feature-length treatment in No No: A Dockumentary, which premiered at the Sundance Film Festival in January and is available on VOD Sept. 2 and in select theaters Sept. 5; you can watch the exclusive trailer above.

Jeff Radice’s doc includes extensive interviews with Ellis, who died of cirrhosis of the liver in 2008 at the age of 63. Ellis played professional ball from 1968-1979 for the Pirates, New York Yankees, Oakland Athletics, Texas Rangers, and New York Mets. He helped the Yankees reach the 1976 World Series, and his “flashy” persona drew comparisons to boxing great Muhammad Ali.

Speaking of greats, the film’s score was composed by Rock and Roll Hall of Famer Adam ‘Ad-Rock’ Horovitz of the Beastie Boys.
