I would imagine the best way to get start writing about getting involved in your local scene, is to start being part of the local scene. I applaud people like yourself who have this desire to be part of the local scene, because I think it makes jumpstarting a music career so much easier. With that said, I have some suggestions that hopefully will help.
First, I think you're starting great by documenting your journey to create your first album.
Since you want your next blog post to be a guide on how to get involved in your local scene, if you don't have that experience yet, create a pre-cursor article talking about how you don't know how to do that yet, but as an artist you're figuring it out.
Talk about the things you plan to do to become part of the local scene, why you've started to get back into it, etc. This can be a series, like part 1, part 2, etc.
Maybe, it'll be in part 2 where you start talking about the first thing you've done to be get involved in the local scene, how long it took, etc. Bring people along for the experience.
I think there's stuff you can do with social media to have people join in on the experience and build your fanbase, but it might be better sticking with the website to start. It's up to you really with how far you plan to take things.
I saw on your music bucket list, doing an open mic night is listed #5.
Now, I don't know NYC or the NY area at all, but I asked my world traveled friend Google, and it listed a bunch of places you might want to contact or look into so you can cross that off your list, and start building your fanbase for your album.
Even if you just do covers and not originals, it'll help. Here's the link I found https://www.nyc.com/best-of-new-york/best_open_mic_nights_in_new_york.2159/42/
I don't know your genre or style of music you plan to do, but I did see you write more about hip-hop and R&B music. If you plan to do the same or similar style, it looks like the Nuyorican Poets Cafe is one of the places to be to get involved with. Here's the link to them I found: https://www.nuyorican.org/hip-hop/
If you're finding it tough to get into the local scene yourself, or you're just not feeling ready, try reaching out to the producers, managers, artists, etc. via social media or email.
Tell them you're a new artist in the industry blogging your journey and you'd like to ask them ONE question about the music industry that would help aspiring artists and feature the interview on your site. Don't tell them the question until they reply back to you. Instead, tell them if they're interested in taking the time to answer the one question, reply back and you'll send it to them.
Now, it doesn't have to be 1 question, but it's a little different and it won't take up too much of their time. It might also get their interest piqued to reply back by you not telling them the question up front. Of course, it could be 3 questions or 10, but I'd say the less the better, just to be respectful of their time and yours.
It's up to you if you want to say this next part or not, but you could also mention since you're just getting started, you currently have about 60 readers per month, but you're growing. You think with the advice they have to offer, could really help upcoming artists.
Also, I don't know how accurate that number is regarding your site readership, because it was really hard to find some stats online in the normal places for your site, since you don't have a ton of visitors per month. So, the only place I could find numbers was https://mysitewealth.com/soundsdiscovered.com.html
That site says 2 unique per day, so I just multipled by 30 days.
Now, what's a good number of people to contact for this?
I'd say not to stop at 1 or 2, but 100 might be overwhelming. Just know you need to contact enough people to start getting traction. It should also be fun for you and it will check off some more boxes on your bucket list.
Another place to find venues to check out and artists to reach out to, try SonicBids: https://www.sonicbids.com/find-bands/?location_radius=1&location_geo=40.71427%2C-74.00597&location_str=New+York+City%2C+NY
You have to create a free account to their names and social media info.
If they're active on social and their following isn't so huge where they might actually reply back, hit them up. Heck, it might also be worth it for you to reach out to more well known artists you like, Gourdan Banks.
Typically, because most celebs and artists don't reply back, you can get your feet wet and get over any fears you might have about contacting people.
When you get responses replying back to you, ask them the question you want to ask and thank them.
A little hack you might want to also throw in after you get their answer to your question and their feature goes live on your site, ask them if they have any friends they know who would like a feature on your site.
This could be a good way to spread your name as a musician and grow your blog if they send friends your way.
Lastly, and just for fun: #27 on your Music Bucket List regarding becoming more familiar with classical artists, you might want to check out this course https://www.coursera.org/learn/introclassicalmusic
TLDR - become part of the local scene by going to open mics, music events and get contact information from social media and places like SonicBids to connect with artists, producers, managers, etc.
