- "Wall of Sleep", Daniel Avery + HAAi
This came up on Tidal's new releases stream and I just really liked it. A voice floating in a sea of shimmer pedals. If people had never stopped making trip-hop maybe it would sound like this by now.
There's an official upload of this on YouTube with cool analog video accompaniment, but the sound quality (mastering?!) on that version's real bad. Maybe pull that up and watch it simultaneously with the Bandcamp version, but muted.
- "Non-Entity" (ReAct Now), Nine Inch Nails
This song was recorded, and rejected, for With Teeth, and went unheard until September 2005 when MTV held a benefit concert for victims of Hurricane Katrina and Trent Reznor (a longtime New Orleans resident) showed up and played this incredibly haunting version solo on piano accompanied only by a drum machine. (The studio version, which did get posted on NIN's website some years later, is actually a lot less interesting.)
The chorus chord progression was later used in "34 Ghosts IV", so this is technically the original version of Old Town Road.
- "Cymbal Rush" (Henry Rollins Show), Thom Yorke
Thom Yorke's solo stuff tends to a stripped-down production style, seemingly limited to whatever electronic gear Yorke can program himself. This is often stark and impactful, but in the case of the album version of "Cymbal Rush" it just feels undercooked.
But then there's this incredible one-off live version, which, given inclusion of Johnny Greenwood and Nigel Godrich (watch at 2:50) I guess is basically what "Cymbal Rush" would have been if it were a Radiohead song.
- "New Jazz Underground Live! #2, New Jazz Underground
These are some dudes who crowdfund recording their jazz band performances and posting them on YouTube and they just happen to be super good. I found them through a track they called "Sad Boy Anthem" but they've got a bunch of these full-length 50-minute-ish "Live!" performances up and that's the real gold. I listened to a few of their livestream sets and this one was my favorite.
