The parish has been celebrating the modern Roman liturgy in a reform of the reform context for quite some time now (and to great acclaim) and from what I understand, they will now in addition begin celebrating the usus antiquior on a semi-monthly Sunday basis, alternating it as the primary parish Sunday Mass with their reform of the reform liturgy -- if any local reader knows more information, please let the NLM know.
The establishment in parishes of both the usus antiquior and the modern liturgy which is being celebrated in a reform of the reform context -- and in sung forms in particular -- is certainly something to be encouraged and fostered, and it seems very much in keeping with the vision of Pope Benedict XVI.
The blog Chris & Co. have some images up from the first of the new Sunday Masses to be celebrated.
