Among the headphones you are looking for, the Denons are are closed-back headphones. Any other serious headphones--Sennheiser, Grado, AKG, Beyer--are open-back designs.
For informed descriptions of any headphone you might be interested in, go to http://www.headphone.com, the website of Headroom.com.
In addition to those Denons, I would look at their descriptions of the Grado RS-1, Sennheiser HD 600, Sennheiser HD 650, and the AKG K 701.
Being a drummer too, I have long been satisfied with the open, fast, airy, extended, and completely natural sound of the Sennheisers I mentioned.
