I have a chord progression in the key of C, which walks up from the IV chord up to a particular variation of the V7 chord, which I'm trying to name in a helpful way for a lead sheet. Here are my voicings on piano, split between the left hand (LH) and right hand (RH)
Fmaj9 (LH) F – (RH) E G A C
F#7b5 (LH) F# – (RH) E F# A# C
G ??? (LH) G – (RH) Eb F Bb C
This chord resolves to an Abmaj7 as the bVI chord in Cm, so I think of it as a dominant and not a minor with an alternate bass, even though the guide tones might suggest otherwise. I see it as something like either a G7#5#9sus4, or a Cm7add11/G.
I also notice that it happens to look like a quartal voicing starting on G if it were inverted out of the close voicing it's in now.
Do either of these seem right? What's the most helpful name for this chord?
EDIT: To give you some context, this is a rehearsal of the song in question: http://www.memoirsband.com/mp3/Time For Nature.mp3. The progression happens at the top of the opening section, just after the first six chords.
