I totally can.
23 Skidoo - The Gospel Comes to New Guinea is the only album I have, since I can't find much of them (An issue I have with much of this list) Although if you find anything else, surely download it/buy it.
Alcatrazz - I definitely reccomend Vampire State Building, but once again, get anything you find. In fact, just assume that the statement "get anything you can find" is after most of these.
AMON DÜÜL - Psychedelic Underground.
AMON DÜÜL II - Yeti is amazing.
Behold the Arctopus - Nano-Nucleonic Cyborg Summoning is my favorite, but there's only two, so.
For Bill Laswell, I really, really like his work with MJ Harris called Digital Sonority, and he also did an ambient album WITH THE DALAI LAMA. Get it if you can find it (Or if you have DC++, I will totally send it to you)
Buckethead - His Praxis work is fairly simple to get into, as is his stuff with Les Claypool (Colonel Claypool's Bucket of Bernie Brains). There's a huge difference between all his albums, some are ambient, some are avant thrash things, so. check out his Wikipedia page
HERE for a full list of all the stuff he's done.
for Can, Tago Mago is my personal favorite album.
Coil - Horse Rotorvator is amazing.
Current 93's Cats Drunk Off Copper is a good starting point, but their discography is pretty vast, and it's generally an ass to find alot of it. Cats Drunk should be pretty easy to find though, in terms of C93.
Death in June - I started with Rose Clouds of Holocaust, and I don't have super much of their stuff. Khar, you want to give me an answer for this one?
for Eels, I think Beautiful Freak or Daises of the Galaxy are good starting points, although Electro Shock Blues is definitely their best album.
El Stew only have two albums (to my knowledge), and both have Buckethead. So yeah.
Electric Wizard, definitely Dopethrone. It is easily one of my favorite stoner albums ever. for Acid Bath, I kind of switch between Paegan Terrorism Tactics and When the Kite String Pops as the better album. I'm currently edging towards When THe Kite String Pops, but that opinion changes.
Ephel Duath - I really like Pain Necessary to Know, myself, but I only have that, Phormula, Rephormula, and Painter's Palette.
Crotchduster only have one album, Big Fat Box of Shit. Definitely get it.
for Mike Patton stuff, I reccomend Mr. Bungle's California album to start.
Foetus are interesting. They go under a multitude of different names (I think a different one for every album pre 1996 ish, but I could be mistaken). All of them have Foetus in the title though. I happen to really like Gash, but it's all really good stuff.
Gabby La La only has one album. Get it. I mean, small Asian girl with a sitar and a toy piano riting songs about the mailman and shoes? Shit, even the silly indie kids would probably love it.
John Zorn's discog is unthinkably vast and varied, and for me to pick out one album would be insane. That being said, the first album I got was Naked City's Torture Garden, which is, basically, crazy grindcore with a saxophone.
Legendary Pink Dots are amazing. I really love All The Kings Horses, personally.
Maudlin of the Well's Bath is my favorite. Although I still have to check out their latest post Maudlin name material.
Nash The Slash is a motherfucker to get anything by. I don't even have an actual album, just a collection of songs. Bleh.
Nurse with Wound's discog is pretty massive too, and for me to pick out any specific album would be murder. Pirate every album you do find, and I can tell you that you won't be disappointed.
Oingo Boingo's Nothing to Fear is my favorite Boingo album.
for Praxis, definitely get Transmutation. It's great.
Primus' Frizzle Fry is generally the accepted best album, although for me Pork Soda edges SLIGHTLY above it just because of some very good memories attached to listening to that.
for Les Claypool, the aforementioned Primus albums, plus his Fearless FLying Frog Brigade; Ignore the studio album, they're much better live and their bootlegs are really easy to find. Just google it.
Psychic TV, really, just get whatever you can. I don't have enough of them to reccomend anything specific.
Skinny Puppy, I really, sincerely reccomend Too Dark Park. I do believe it's their widely accepted best album, and I'm inclined to agree.
Sleepytime Gorilla Museum - Of Natural History is great.
Sun Ra released WAAY too much stuff, but I very much reccomend both Nuclear War and Other Planes of There or Space is the Place to get a good view of how diverse it is.
Throbbing Gristle - I really like Nothing Short of a Total War.
