She has written an extended preface for a forth-coming multi-volume critical edition of Becker’s organ works (Wayne Leupold Editions) and has been asked to submit a monograph on Becker as well. 

Upcoming and recent performances for the 2014-2015-2016 calendar year include Sainte-Croix in Orléans, France; Dallas (Texas) with Pipedreams and the Texas Camerata; Chicago, Illinois at Loyola University; Ft.

Recorded in Pithiviers, France in 2010 at the newly renovated historic Cavaillé-Coll organ of the church of Saint-Salomon-Saint-Gregoire de Pithiviers, the disc has received wonderful reviews. The 2011 September/October issue of Choir & Organ magazine gave it five stars, writing that “Damin Spritzer serves both instrument and music well, alert to the music’s lyrical mien and harmonic muscle, negotiating the III/49 machine with an easy command of drama and a real feeling for Becker’s melody-led, cleanly-executed music…A second volume is eagerly awaited.” The AAM Journal wrote, “The music comes alive under her touch!...This recording is a delight...” And a review from Classical Music Sentinel praised the recording, saying “…Damin Spritzer drives the music along with plenty of forward momentum which adds a singing quality to the melodic lines and an assured rhythmic movement to the toccatas and marches...the final glorious chord of the Marche Triomphale will make you glad you’re alive.” 

Her second volume of Becker’s organ music was released in November of 2014 for Raven Recordings, and was recorded in Orléans, France in April of 2013 at the Cathédrale Sainte-Croix d'Orléans. It received four stars from Choir & Organ, and the following praise from Classical Music Sentinel: “…Spritzer jumps right into the action with an assured confidence and refined musicality that quite simply reinforces the high level of craftmanship and beauty inherent to the music of composer René Louis Becker...The opening Toccata in B-flat alone, which could easily intimidate many organists with its agitated left-hand and busy pedal work, moves forward at quite a pace under Spritzer's command, and thus reveals its determined musical lines all leading to a powerful finish…her choice of registration for the softly tender Cantilène, Op. 63 demonstrates an organist who knows how to balance colors on a sonic canvas… Both volumes belong on the shelves of all organ music enthusiasts.” Two more recordings of Becker’s music are planned for the coming years, as well as a number of collaborative projects. 

Dr. Spritzer has been heard on Michael Barone’s nationally-syndicated “Pipedreams®” radio broadcast on programs including: Historical Eclecticism in Houston, Prayers and Alleluias, Twenty-Somethings, Merriment at the Meyerson, and “Pipedreams: Live!” performances at the Meyerson Symphony Center in Dallas, Texas in 2005, and at Saint Michael and All Angels in November of 2014.
