Robert Altman's masterpiece Nashville is on blu-ray today, and you owe it to yourself to check out this film, which is one of the most visceral and immediate representations of America ever made. It follows five days leading up to a country music concert in Nashville, TN and no less than 24 characters are chronicled as their stories interweave themselves in and out of the frame. When it all comes together it achieves greatness in ways you couldn't possibly predict ahead of time. Nominated for 5 Academy Awards and my favorite Altman film.
