Tomorrow's the 4th of July, and we can't think of anything more American than Johnny Cash. We haven't been able to score a pre-release copy yet, so you can bet we'll be in line tomorrow to buy this album. American V: A Hundred Highways ($11) features the last song the Man in Black wrote before his passing in 2003. Like its predecessors, the album was produced by Rick Rubin, and has a tremendously strong first single in "God's Gonna Cut You Down."
