My thoughts, so far.
Writing is great, and the dialogue is some of the best I've seen in a VN so far. Even with the sillier moments, nothing seems out of character for anyone. As ridiculous as some of the situations get, it always feels grounded. The scene really reminds me of back when I was in bands in the Chicago scene in the late '80s, and early '90s. Well, minus the almost universal homophobia and misogyny.
I am worried that I'm already falling pretty hard for 3 of the main girls, and do not look forward to having to choose.
Mary is great, and probably the one I'd probably want to date in real life, though I think her parents are foreign spies of some sort. Getting serious "The Americans" vibes from them.
Lita is someone I'd never date, but as a fuck-buddy would be kinda like the library chick.
Lane is amazing looking, and I want a ton more sex scenes with her. Need a lot more time with her to see more of her personality, but she's one of my favorites so far.
Caitlin is almost perfect, and I love how conflicted her brother is about the whole thing. Plus, I think she gives the best chance at a multiple LI ending, as those pics she hid from the MC seemed to show her ogling her girlfriend a bit.
Sloane is the only main girl I'm not interested in at all romantically, but I kinda want her to be in every scene, just being herself. I am really interested to find out whatever secret Rose tells her she needs to share with the MC.
Seok is really interesting, and I hope the MC can get help for her without landing him & the rest of the band in jail. Don't know if she could be an LI, since she's not listed in the Developer Notes in the OP. I got serious trafficking vibes from her situation, and I'm not sure her "dad" is actually her dad, but her "sponsor" and who she owes money and/or labor to for bringing her into the country. I could be totally wrong, but that's the vibe I get from her story.
Overall, this is a game I really hope gets finished, and am seriously considering supporting. The only thing holding me back is the time it took between updates.
