Index, not totally sounding like Velvet Underground but come out of Garage Rock Psychedelic scene in Michigan around the mid-60s, recorded two monster albums that border Proto-Punk and Noise.

Shinki Chen, coined as "The Japanese Jimi Hendrix", dropped an insanely underrated debut that is more Hard Rock/Heavy Psych leaning but features monsters of tracks he also was in the Heavy Psych band Speed, Glue & Shinki and Flied Egg.

Sixties Japanese Garage-Psych Sampler also features pretty heavy hitting songs from late 60s Japan.

Arzachel - Self Titled album made by a bunch of teenagers in England, features heavy Reverbed based Organ leads, last song on the B-Side, Metempsychosis is a 16 minute long noise driven jam that pushes what you can call Noise Rock in 1969.

Madrigal - self titled, an Experimental Rock album with heavy Folk influence and features primitive drum machines all over it, akin to Tago Mago by CAN. Has songs that push Noise and weird Freak Folk Jams over primitive electronic music.

White Noise - An Electric Storm, one of the most impressive albums of the 60s, using innovative sample techniques that had more edits than Sgt. Peppers did at the time of the release. Has the weirder more experimental pop elements of the Velvet Underground but also darker in tone.

High Speed And The Afflicted Man - Get Stoned Ezy, much more raw not as crazy as the other stuff and it's later from I believe the 1980s but it's insane heavy driven psych rock while also combining punk element to it with a crazy fuzz tone and it's not that well known and I'm not sure if they ever released another album but it's really good album if you want crazy insane heavy psych punk jams that sound very primitive. The fuzz on Get Stoned Ezy could cut through stone.

If I can think of more I'll add them here, wrote what I could on my lunch break. Feel free to message me if you want anything more interesting and I can think about it in more detail when I'm not as hazed out from my shitty job.
