The idea of releasing or getting rid of anger is part of the Western idea that by releasing the energy the person will feel better and their life will be healthier. My approach is that it is not possible to get rid of energy and physics also teaches that we cannot create or destroy matter or energy. In traditional Native thought it is unthinkable to get rid of the anger, sickness, addiction and so on. What I ask patients to do is to make a conscious relationship with the anger. This requires that the patient introduce themselves to the anger and give it a gift. The gift in the Native American tradition usually is in the form of natural tobacco. Intent is more important than the actual form of the physical gift.  The gift is a ceremonial form that allows our ego life to transcend and make relationship with spiritual entities. In Tibetan Buddhism it is also customary to give gifts to the Deities in the form of grain, butter lamps and such. Natural law dictates that the energy of anger must respond by introducing itself. Once the relationship has become conscious the person can ask anger what it is trying to teach them in this life time. Therefore, the anger becomes an ally that can help the person move into higher consciousness and not something to rid themselves of. Especially since it is not possible to get rid of this energy.
