Karen Marrolli for her 2010 thesis on McGlynn writes: "Throughout all of McGlynn's work, while there are a good amount of compositional thumbprints and overarching characteristics, there also is a great deal of variety. This is an incredibly refreshing aspect to McGlynn's choral writing. Various constant influences are present in his music and give his canon a sense of identity; however, he does not simply reconstruct successful pieces over and over again in an attempt to rest on his laurels. His body of work displays a great range of techniques and musical ideas and continues to develop and mature. Further study of some of his more recently recorded works, such as "O Maria" and the brilliant work "Victimae" (both released on the 2009 Anúna CD "Sanctus") would reveal how his musical influences factor into his compositional efforts in ever-evolving ways. This continuous growth bodes well for the longevity of this composer as he takes his place among the important composers of our time.
