This video demonstrates how to enter a new session using BRIAN. The video is 4 and a half minutes and covers entering a new session from beginning to end using the Gigi Gryce session of June 7, 1960 for the Rat Race Blues album.
The video shows BRIAN used on a Mac, but the Windows version is very similar. Windows users should have no trouble seeing the correlation. The biggest difference between the Mac and Windows version is that Mac uses a dedicated menu bar at the top of the screen while the Windows version has the menu bar integrated into each window.
