Injuries and RehabTell us where it hurts! Do a quick search before asking about your shoulder injury to make sure your question hasn't already been answered (about 50 times), and read the sticky post first.
To work on the soft tissue in your middle and upper back, foam rolling or tennis ball rolling works great. (what follows is a video of Mike Boyle using the two tennis balls taped together method)
Dynamic mobility drills are designed to improve joint movement and muscle length but are done with movement instead of prolonged holding of a position (aka static stretching).

For dynamic mobility stuff, I have heard great things about Magnificent Mobility by Mike Robertson. I don't have it, but I have his Bulletproof Knees and Building the Efficient Athlete. Both are great.
For myself, I get all my mobility work from Scott Sonnon's Intu-Flow.
Cheers,
Adam
