oh yeah, any early daniel johnston...

"You can't buy respect like the librarian said."

There are some bands that work better on the lofi medium and some better on the hifi medium.

Flying Saucer Attack....

high rise - abstract

darkthrone - transilvanian hunger
voivod - rrröööaaarrr
celtic frost - morbid tales
bathory s/t
venom - welcome to hell, in league with satan, black metal
mayhem - pure fucking armageddon (although it is a demo)
possessed - 7 churches
exodus - bonded by blood
early anal cunt
carcass - reek of putrefaction
zyklome a - noise & distortion
anything by the urinals


there are so many

this is true. i like both but lean towards the no fi sound.

Halo of Flies
Drunks With Guns
The Thrown Ups
Beherit (at least on Oath of Black Blood)
The Shitlickers

EDIT: a misprint in one of the band names, that is now corrected year and a half later.

I was always embrassed at the quality at myspace.com/theprivileges, but it may be your bag. If not, sorry to waste time.

the early grindcore stuff (napalm, carcass, bolt thrower)
early half japanese

Keith Richards recorded the basic acoustic guitar track for "Street Fighting Man" on a tiny cassette recorder.

SyrFox - Fox #8
SyrFox - Stations
SyrFox - Rain
SyrFox - Cloud Mountain
SyrFox - Please Hope For A Peaceful Riot To Come!

And also that SyrFox's forthcoming album I heard the leak of

The Skaters

Ariel Pink's Haunted Graffiti .... lo-fi psychedelic pop... all his percussion is made with his mouth... Ive been obsessed with it for a month straight now

Terveet Kadet's first two 7 inches.

Basically any of the LLN blackmetal bands...

i think this is the first recommendation that i'm not familiar with already.
the rest of you need to work harder.
