It's great she's working in a studio right now, I'm really happy to see that. However, there are some combos of voices that meld together beautifully (Stevie/Chris, Stevie/Lindsey, Stevie/lots of other people ---- ) but unfortunately I don't hear Stevie/Dave's voices melding all that well.
But hey it's an early version still....
PS - Please please make the synth-strings go away.
Best of luck to Stevie on this project!
