Drone recommendations

Well, by my estimation, you should be checking out Earth (excellent) and Khanate (maybe). Just be willing to listen to anything. Ragas can be appealing from a drone perspective, and I fully believe it. Wow. Also, Merzbow's drone cannot fail.

Bowery electric
flying saucer attack

Alvin lucier - Music On a Long Thin Wire
Loscil
Necropolis - Necrosphere is also interesting drone
recorded in abandoned siberian missle silos. You can find it here: http://fuzzygroinland.blogspot.com/2007/01/necropolis-necrosphere.html

Nanohex. Few releases can be found around the net.

Bull of Heaven

These are the longest, droniest pieces of music I've ever heard of (one of them is 24 hours long). Some of this borders on "drone metal," just barely.

AUN/Multigone

This seven track disc is undeniably the heaviest music that AUN has created so far, a grinding, distorted soundscape that begins with the keening electronic drones and muffled, disembodied metallic riffing that becomes endlessly tanged in a nest of squirming low-end noise in the opening title track, and steadily ratchets up the heaviness with each track, until we come to the punishing "Palejoy", a bludgeoning Industrial metal dirge that has massive, Godflesh-like percussion fused to processed, almost synthetic sounding doom riffage, a black cloud of buzzing, ultra downtuned black dirge drifting over a muffled, slow motion breakbeat. In between, AUN erects vast walls of crumbling distortion and rhythmic guitar loops forged into apocalyptic ambient drift streaked with heavenly synth choirs and sweeping cosmic fx, crushing fifteen-minute blasts of immolating amplifier ragas formed from a nebula of melting woodwind sounds, distant elephantine tympani drums, hellish symphonies of rusted, scraping strings and celestial electronic whiteout that ends up sounding like something from Skullflower's Orange Canyon Mind but one hundred times heavier, and strange deep-space blues jam instrumentals with impossibly detuned guitar soaring through black holes of reverb and tape fluctuation.

This is seriously crushing stuff that stands out in sharp contrast to the hordes of amp-leaning feedback riders, and is highly recommended to anyone into KTL, Final, Black Boned Angel, To Blacken The Pages, K.K. Null, Aethnor, Fall Of The Grey Winged One, Fear Falls Burning, Hlidolf, Messiah Complex, and other heavy, textural industrial/ambient/sludge groups.

Multigone is packaged in the signature Bliss sleeve with full color artwork, and the disc is attached to the interior of the sleeve on a plastic hub. Issued in a limited edition of 300 ...

For Coil-like drones I reckon you should go for:
Nurse with Wound - Soliloquy For Lilith
Mount Vernon Astral Temple - Musick that Destroys Itself

and my current favourite drone record...
Emeralds - The Solar Bridge

Emeralds, are extremely good
