Information: - Hydra Head Records is an independent record label that specializes in extreme metal music, founded in New Mexico by Aaron Turner (the frontman of Isis) in 1993. It has another imprint, Hydra Head Noise Industries, which specializes in experimental and noise music. - Post-metal (or metalgaze) is a stylistic fusion of heavy metal with post-rock and/or shoegazing. Hydra Head Records owner and Isis frontman Aaron Turner originally termed the genre "thinking man's metal", demonstrating that his band was trying to move away from common metal conventions. Due to the experimental nature of post-rock and shoegazing, post-metal is closely related to avant-garde metal. - CD-R (Compact Disc-Recordable) is a digital optical disc storage format. A CD-R disc is a compact disc that can be written once and read arbitrarily many times. - Compact disc (CD) is a digital optical disc data storage format released in 1982 and co-developed by Philips and Sony. The format was originally developed to store and play only sound recordings but was later adapted for storage of data (CD-ROM). Several other formats were further derived from these, including write-once audio and data storage (CD-R), rewritable media (CD-RW), Video Compact Disc (VCD), Super Video Compact Disc (SVCD), Photo CD, PictureCD, CD-i, and Enhanced Music CD. Audio CD players have been commercially available since October 1982, when the first commercially available CD player was released in Japan. - Aaron Turner (born November 5, 1977) is an American musician, singer, graphic artist, and founder of label Hydra Head Records. He is most widely known for his role as guitarist and vocalist for the post-metal band Isis, while also participating in several other bands and projects such as Old Man Gloom, Lotus Eaters and Split Cranium, a collaboration with Jussi Lehtisalo of Finnish band Circle who toured with Isis in 2009. - Old Man Gloom is a sludge/doom metal/post-metal band originally formed in Santa Fe, New Mexico, United States, but now based in Massachusetts. The group, formed by Aaron Turner of Isis and Santos Montano, has now expanded to become a sort of supergroup in the Boston hardcore and metalcore scene. The group is less a band than it is a recording project for a variety of talent. By the release of their first album ("Meditations in B"), Old Man Gloom expanded to include two new members. - The Sawblade EP ( also called the Buzzsaw EP ) is a handmade CD - R made by Isis for their tour with Neurosis and Candiria , limited to 200 copies ( the first 40 with red blade inserts , the remaining 160 with black ) . It was sold at these shows at a limit of 15 per night , and the leftover copies were given to friends of the band as a year - end '' thank you '' gift . The vinyl run of this release was limited to 250 copies . As such , Aaron Turner does n't consider this an ' official ' Isis release , describing it as '' more like a special artifact for us and the few converts we had at the time '' . '' Emission of the Signal '' and '' House of Low Culture '' were both constructed by Aaron Turner and Jeff Caxide at home ; '' Streetcleaner '' and '' Hand of Doom '' are both covers of Godflesh and Black Sabbath , respectively . The former was recorded for Isis ' 1999 split release with Pig Destroyer , while the latter was recorded during the Red Sea sessions in the same year . The CD version of the release was a genuine sawblade with a CD physically attached to it , which several venues prohibited from sale . To the best of Turner 's knowledge , '' no one was ever injured by one of these '' . The Japanese double release of Mosquito Control / the Red Sea features both cover songs as bonuses ; '' Streetcleaner '' appears at the end of disc 1 ( Mosquito Control ) , and '' Hand of Doom '' appears at the end of disc 2 ( the Red Sea / 1998 Demo ) ; both tracks were later selected for inclusion on posthumous b - side album Temporal . - In computing and optical disc recording technologies, an optical disc (OD) is a flat, usually circular disc which encodes binary data (bits) in the form of pits (binary value of 0 or off, due to lack of reflection when read) and lands (binary value of 1 or on, due to a reflection when read) on a special material (often aluminium ) on one of its flat surfaces. The encoding material sits atop a thicker substrate (usually polycarbonate) which makes up the bulk of the disc and forms a dust defocusing layer. The encoding pattern follows a continuous, spiral path covering the entire disc surface and extending from the innermost track to the outermost track. The data is stored on the disc with a laser or stamping machine, and can be accessed when the data path is illuminated with a laser diode in an optical disc drive which spins the disc at speeds of about 200 to 4,000 RPM or more, depending on the drive type, disc format, and the distance of the read head from the center of the disc (inner tracks are read at a higher disc speed). Most optical discs exhibit a characteristic iridescence as a result of the diffraction grating formed by its grooves. This side of the disc contains the actual data and is typically coated with a transparent material, usually lacquer. The reverse side of an optical disc usually has a printed label, sometimes made of paper but often printed or stamped onto the disc itself. Unlike the 3-inch floppy disk, most optical discs do not have an integrated protective casing and are therefore susceptible to data transfer problems due to scratches, fingerprints, and other environmental problems.
