Paul J. Sifler, born in Ljubljana, Slovenia, immigrated to the United States at the age of 11, and following his studies at the Chicago Conservatory of Music, led a long and prolific career as a composer and organist. This Offertory for Marimba is one of the movements of his Marimba Mass (Mass for SATB Mixed Choir and Marimba), composed as a cadenza of sorts.
