Sounds a lot like this masterpiece:
From Wikipedia...
...As a radical departure from the rest of Reed's catalog,
Metal Machine Music is generally considered to be either a joke, a grudging fulfillment of a contractual obligation, or an early example of
noise music. The album features no songs or even recognizably structured compositions, eschewing
melody and
rhythm for an hour of over-modulated
feedback and guitar effects, intricately mixed at varying speeds by Reed himself. In the album's
liner notes he claimed to have invented
heavy metal and asserted that
Metal Machine Music was the ultimate conclusion of that
genre. The album cost Reed credibility in the music industry while simultaneously opening the door for his later, more
experimental material...
....According to Reed (despite the original liner notes), the album entirely consists of
guitar feedback played at different speeds. This can be heard clearly if the album is played at 16 rpm with the balance adjusted to hear either the right or left channel only as each appears to be unrelated. The two guitars were tuned in unusual ways and played with different
reverb levels. He would then place the guitars in front of their amplifiers, and the feedback from the very large amps would vibrate the strings — the guitars were, effectively, playing themselves. He recorded the work on a
four-track tape recorder in his New York apartment, mixing the four tracks for
stereo. In its original form, each track occupied one side of an LP record and lasted exactly 16 minutes and 1 second, according to the label. The fourth side ended in a
locked groove that caused the last 1.8 seconds of music to repeat endlessly (as had been done on John Cale's recording of
Loop as a
flexi-disc accompanying an edition of
Aspen in late 1966). The rare
8-track tape version has no silence in between programs, so that it plays continuously without gaps on most players. A
quadraphonic disk was also released by RCA....
