BLR themselves. Somehow they've managed to release ten videos, the last two about 4 weeks apart. That's writing lyrics, new music, editing, recruiting singers and musicians. And somehow no one still knows anything about them.
And that's not just writing lyrics and music, that's writing lyrics and music that match an already made video and fit nearly perfectly with the real singer's lip movements while still being coherent (albeit with Word Salad Lyrics), as well as finding singers who sound just like the people in the videos. So they somehow watch the real videos with no sound, and come up with a completely different interpretation of what's going on the video from scratch, all while making a song that's far catchier and more impressive than the original (that, of course, is YMMV). If that's not the work of some absolutely brilliant musicians, I don't know what is.
Even better? It's one guy. Music, voices, editing, everything is done by ONE GUY. And yes, he even does the female parts.
Releasing two videos in one day after not having a video for three weeks. If that's not awesome...
'Yeti' takes the video editing Up to Eleven by adding whole footage cut from cloth, and somehow making bits with Chris Martin chasing a Wookiee into a forest just to... Well, it's equal parts CMoA and Crowning Moment of Squick, really...
The song itself is actually fucking epic, for a love song between a guy and a yeti.
Watch "Morning Dew" and pay close attention to the part of the video when Bruno Mars sings the lines "the world's fastest girl might be wrong / we popped the cork, now it's time to go away", especially to what the monkeys are doing in the background: It becomes obvious that you're seeing the same scene played forwards, then in reverse... Meaning he wrote lyrics that matched with backwards lip movements.
He does the same thing with the entire bridge of "Beard With Glue," which is the chorus reversed. "Who do you think would win in a bear fight, in the night?" He actually does this quite a bit.
"Morning Dew" somehow manages to combine Bruno Mars, Lady Gaga, Jay-Z and some of the most nonsensical lyrics ever, and the resulting song is totally badass.
All three Star Wars-based BLRs. For one, allthreevideos were uploaded on the exact same day, following a period where a video might've come out every 2-3 months. For another, they got Bill Hader, Maya Rudolph, and Jack Black to provide guest voices
