The Martinez Progression

The Martinez Progression is a chord progression invented and used by Gilbert Martinez, who is its namesake.
The Martinez Progression is as follows:
:i-iv-V-i-iv-V-V7-I-I7-iv-ii°-V-I
If in the key of C, this translates as follows:
:Cm-Fm-G-Cm-Fm-G-G7-C-C7-Fm-D°-G-C
:
This is a progression that appears in some of Gilbert's songs, especially those in the key of C minor. He says, "I first heard it in a song we tried out in band during my junior year of high school, known simply as Toccata. It was a song done in the style of Girolamo Frescobaldi, and it was beautiful. It's what got me into Baroque music and Frescobaldi's works. Ultimately, we ended up not playing it for a concert, and that was kind of a shame. My usage of its chord progression in songs is my way of performing that song, as well as a call back to my junior year." The Martinez Progression is a slight variation of Toccata's progression.
The Martinez Progression appears the songs "Toccata alternativa prima di Messa," "Hoc Vae Mihi Est," and "Deus Benedicat Eum."
The first song is the second song featured in Cristo Re, which was a collection of organ music dedicated to his local church. The latter two songs are part of a collection of songs composed in March 2015 for Gilbert's play Beneath the Moon of Dripping Blood, which focused on the death of an indignant vampire in 1589. All three share the Baroque style of emotion.
