This the transcription of this etude written by Warren Nunes and played by @Eddie Lastra. This is an etude chorus over the standard Corcovado (Quiet Nights Of Quiet Stars). In the first part he plays the theme, the 2nd part is an eighth note chorus and the 3rd part is a sixteenth note chorus. Eddie Lastra was a student and a friend of Warren Nunes. It's full of good ideas and licks for bebop vocabulary, and it's good way to understand how to improvise over this...
