It is the first album released by the group since their debut performance on EastWest '77.
[citation needed] Notable American jazz musicians, The Brecker Brothers and David Sanborn, contributed to the album.
The cover depicts two race cars battling on a circuit, possibly Fuji Speedway's hairpin turn.
[1][better source needed] The cars are late-1970s Group 6 sports prototypes from the Japanese Fuji Grand Champion Series, most likely a Lola T290 -Mazda[2] and a March 74S[3] from the 1978[4] and 1979[5] championships, respectively.
[6][better source needed] While the cover itself featuring two race cars is used extensively on all currently existing releases (including the 2021 clear orange vinyl reissue), there was the original cover (and the first pressing) featuring a picture of the band standing with pills falling in front of them, with different pictures on the insert (the insert notes remained the same as later pressings) and a red circular cover art with yellow numbers on the left (the 1980 reissue pressing features the same picture as the 1st pressing but with different circular cover art, this time featuring an Alfa Records logo on the right).
