Here's a track that will keep you climbing for almost a full four minutes. It's brand new from Dropkick Murphy's and it's every bit as good anything you've heard from them before. At first listen, you'll recognize their familiar sound, but you'll also notice that it's a bit on the slower than some of the stuff you're used to hearing from them, so it works great for a seated (or standing) climb. (80 rpm)
Here's another one from the same album that I'll be using for sprints on the chorus:
Definitely give the whole album a listen and keep them in mind when St. Patrick's Day rolls around!
