Luis Enríquez Bacalov (30 August 1933 – 15 November 2017) was an Argentine (naturalized Italian) film composer and musical director.

The standard Mass text was significantly truncated in accordance with Bacalov's desire that the work appeal to all Abrahamic faiths: Christians, Muslims and Jews.

It had its world premiere in spring 2006, also at Sanders Theatre, performed by the Cambridge Community Chorus (William E. Thomas, Music Director).

Two of his songs, "The Grand Duel (Parte Prima)" and "The Summertime Killer", were used in Quentin Tarantino's film Kill Bill (2003).

Bacalov was the first to write a triple-concerto for bandoneón, piano, soprano and symphony orchestra: Tango Music with Symphonic Proportions.

From 2005 to his death, he was the principal director of Orchestra della Magna Grecia in Taranto, southern Italy.
