One of our favorite Open Mics in Annapolis started doing a Virtual Open Mic on Facebook this week. What they did was create a public group page that everyone who wants to play joins. This gives them the ability to Go Live to the page for everyone watching to see, which worked out better than the initial idea of skipping around to each band's FB page. So, they made a schedule of performers (15 min each) and the host went Live first to open things up, then introduced the next group. The next group then went live on the group page and everyone watched their performance. Then they introduced the next performer, who then went Live. Rinse, Repeat. Worked out pretty good and since each performer went live themselves on the Group Page, they added verbiage to their Go Live post like their band website, Venmo and Paypal links, so anyone who wanted to donate could do so, as many of these folks support themselves in part or in full through their music, etc.
There was a variety of ways that people got sound into FB Live; some were just a solo or duet group with a guitar and a laptop webcam/mic, others were a full band with PA. Some of the bands used a phone or webcam (which we've done on occasion and works relatively well), while others plugged their mixer output into the laptop/PC and used that for FB audio with either a webcam or separate video camera. We're going to participate in the open mic on Monday and will probably just use our phone again to stream us playing through our PA (L1 compacts with analog mixer), but I may experiment with running our mixer's USB output into my webcam-enabled netbook and see how that does.
Mic plug: our Pastors and some of the Band have been livestreaming short webisodes from our church during the week and Wednesdays are a musical webisode. I have to say I'm pretty impressed with the Blue Yeti USB Mic that the Pastor got for his Macbook (running Wirecast to YouTube and FB). It's a multi-pattern mic that we set for stereo mode and put it between a guy singing with an acoustic and a girl singing with piano and it did pretty darn well. Even in the big empty 350 seat Sanctuary it didn't pick up a lot of room noise, but what it did pick up lent some light reverb to the mix which actually worked well. It'd be a mic worth checking out if you want something simple to use to stream a solo or duo act.
