Since its premiere in 1918, Gustav Holst's symphonic cycle The Planets has effectively defined the informal genre of "music about space." But more recently, four prominent artists from different musical realms collaborated on a cosmic exploration of their own. It culminated in Planetarium, which was released earlier this month.

In 1959, the peak of his playing years, Thelonious Monk did something he'd never done before: record music for a film. Released in the U.S. as Dangerous Liaisons, the French film Les Liaisons Dangereuses featured nearly 30 minutes of Monk's music, none of which ever made it to a record. But the master tapes resurfaced last year, and were first released as a vinyl exclusive on Record Store Day this April.
