I love NO BS! They have a great Tiny Desk Concert on NPR you should check out! https://www.npr.org/event/music/191677820/no-bs-brass-band-tiny-desk-concert
I also found a group called Red Baraat via Tiny Desk Concert that has brass. They play sort of in the Bhangra style, I think. Yes, I definitely had to look up their genre, but to me their stuff seems more like Party Bhangra.

I'm not sure what you are trying to find out, but I'm sure it has to do with physics. I play multiple high and low brass instruments and, though I can get a sound out of each with the same embouchure, I do have to change things to get a better sound out of the different instruments. Maybe this link will help you understand what's happening when you buzz into a mouthpiece? https://prezi.com/jybkgihav79d/the-physics-of-brass-instruments/?webgl=0
If you’re not going to play for a while, it’s a good idea to oil the valves before putting the instrument away just to displace any water (or condensation that may form) and prevent corrosion.
If you’re definitely playing regularly, then you probably don’t have to use valve oil that often. It won’t hurt to do it every day, but every couple days is fine as well. You must oil your valves immediately if anything feels “sticky”.
I try to swab my lead pipe (and tuning slide) after playing, but if I’m rushed for time in packing up a late rehearsal I don’t freak if I skip it. I use a silk swab similar to what woodwinds use. However, most players I know don’t bother to do this (or even own a swab). I got into the habit after a friend started doing it religiously because he noticed he was particularly prone to red rot.
I use a Blue Snowball that I got for free at a music convention. It’s not the worlds greatest, but for the price I think it is quite good and versatile. There’s a 3 setting switch on the back so you can adjust the mic according to what you’re recording. I record straight into Audacity, but you can use whatever software you like.

I used to have horribly chapped lips, and now my lips are what gets me compliments the most, so maybe I can chime in here. The best lip balm I have ever used (and swear by) is by Organic 101. Most lip balms have 5-7 ingredients and usually focus on just getting rid of the symptoms for a little while, but Organic 101's has 15 USDA certified active ingredients and heals lips fast; its actually uncanny. I cannot recommend them enough.
.
They offer a 30 day money back guarantee on their products, even on their lip balms. I thought that was funny at first, but damn if they are that hardcore about a lip balm then they probably know what they are doing and convinced me to buy... glad i did.
