"Rush"

From imdb.com and Wiki:

Set against the sexy, glamorous golden age of Formula 1 progressive rock in the 1970s, the film is based on the true story of a great musical rivalry between handsome English playboy guitarist James Hunt (Allex Lifeson), and his methodical, brilliant opponent, Austrian bass player Niki Lauda (Geddy Lee).

The story follows their distinctly different personal styles on and off the sixteen-track, their loves and the astonishing 1976 season in which both retreated to the United Kingdom to record "A Farewell to Kings" at Rockfield Studios in Wales.

They are willing to risk everything to become world champion in a sport with no margin for error: if you introduce synthesizers, lengthy songs reminiscent of miniature concept albums and highly dynamic playing featuring complex time signature changes, you die.

Following mixed reviews, their album “2112” crashes badly at the Nürburgring in 1976 and Lauda loses his hearing in one ear. Hunt sacks his entire pit crew after they mistakently tune his engine in the key of F but finally becomes World Champion when the rain-soaked Japanese Grand Prix has to be abandoned because of fans running on to the track shouting “Wally!” during the quiet bits.

The JPS-Lotus team's druumer Mario Andretti (Neil Peart) makes a late cameo appearance during the closing credits, explaining that he has just finished packing up his 83-piece drum kit and loading it into the truck.
