Question: When was the band of the singer, whose autobiography is called Scar Tissue, formed ?

Context paragraphs:
Arthrofibrosis: Arthrofibrosis (from Greek: "arthro-" joint, "fibr-" fibrous and "-osis" abnormality) is a complication of injury or trauma where an excessive scar tissue response leads to painful restriction of joint motion, with scar tissue forming within the joint and surrounding soft tissue spaces and persisting despite rehabilitation exercises and stretches.  Scarring adhesions has been described in most major joints, including knees, shoulders, hips, ankles, and wrists as well as spinal vertebrae.

Anthony Kiedis: Anthony Kiedis ( ; born November 1, 1962) is an American musician who is the lead singer and songwriter of the band Red Hot Chili Peppers, which he has fronted since its inception in 1983.  Kiedis and his fellow band members were inducted into the Rock and Roll Hall of Fame in 2012.

Pseudopolyps: Pseudopolyps are projecting masses of scar tissue that develop from granulation tissue during the healing phase in repeated cycle of ulceration (especially in inflammatory bowel disease).  Inflammatory tissue without malignant potential, pseudopolyps may, according to Joffe (1977), represent either regenerating mucosal islands between areas of ulceration, edematous polypoid tags or granulation tissue covered by epithelium.  There are reported cases when localized giant pseudopolyposis resulted in intestinal obstruction.

Scar Tissue (book): Scar Tissue is the autobiography of Red Hot Chili Peppers vocalist Anthony Kiedis.  It was released in 2004 by Hyperion and authored by Kiedis with Larry Sloman, who compiled information and conducted interviews.  The book reached a high of #1 "The New York Times" Best Seller List.  An audiobook version, read by actor Rider Strong, was released by Phoenix Audio on June 30, 2006.  An E-book version is also available.

Epidural lysis of adhesions: Epidural lysis of adhesions (LOA), also known as the Racz procedure, is an interventional technique which involves the dissolution of epidural scar tissue by mechanical means to facilitate the spread of analgesics in an effort to alleviate pain.  It is a minimally invasive medical procedure developed at Texas Tech University Health Sciences Center (TTUHSC) in 1989 by Gabor B. Racz.  It is a type of percutaneous adhesiolysis procedure commonly used to treat chronic pain resulting from failed back surgery syndrome wherein scar tissue has formed around the nerves and causes pain.  Evidence suggests the procedure may also be effective in treating spinal stenosis and radicular pain caused by a herniated disc.

Peyronie's disease: Peyronie's disease or Peyronie disease ( ), also known as induratio penis plastica (IPP) or chronic inflammation of the tunica albuginea (CITA), is a connective tissue disorder involving the growth of fibrous plaques in the soft tissue of the penis affecting an estimated 5% of men.  Specifically, scar tissue forms in the tunica albuginea, the thick sheath of tissue surrounding the corpora cavernosa, causing pain, abnormal curvature, erectile dysfunction, indentation, loss of girth and shortening.  A variety of treatments have been used, but none have been especially effective.

Anterior interval release: Anterior interval release (AIR) is a type of arthroscopic knee surgery performed to alleviate pain and associated symptoms caused by scar tissue (or fibrosis) accumulation in the anterior region of the knee, behind and under the knee cap (or patella), in a condition called arthrofibrosis.  In normal, asymptomatic knees, this anterior compartment of the knee comprises mobile, scar-free tissues such as the infrapatellar (Hoffa's) fat pad.  With progression, scar tissue (or fibrosis) leads to closure of the anterior interval, tethering the patella tendon and causing pain, loss of range of motion, damage to knee cartilage, and/or pain, among other symptoms.

Scalpelling: Scalpelling is a body art procedure similar to body piercing for the creation of decorative perforations through the skin and other body tissue, and is most commonly used as a replacement for or enhancement of ear piercing.  Whereas piercing is typically performed with a hollow piercing needle or an ear piercing instrument, scalpelling is performed by using a scalpel to cut a slit into the skin.  Unlike dermal punching, no flesh is removed.  The technique can immediately produce holes with a larger diameter than can be achieved by piercing.  This is a more rapid means of accommodating larger gauge jewellery than stretching, a technique whereby piercings are enlarged by inserting gradually larger jewellery.  Scalpelling is performed to quickly achieve a large-gauge piercing, when scar tissue is preventing further stretching, if tissue has thinned to the point where further stretching could cause it to break, or to combine two closely placed piercings into one hole.

Transurethral needle ablation of the prostate: Transurethral needle ablation (also called TUNA or transurethral radiofrequency ablation) is a technique that uses low energy radio frequency delivered through two needles to ablate excess prostate tissue.  A cystoscope/catheter deploys the needles toward the obstructing prostate tissue is inserted into the urethra directly through the penis under local anesthetic before the procedure begins.  The energy from the probe heats the abnormal prostate tissue without damaging the urethra.  The resulting scar tissue later atrophies, reducing the size of the prostate which in turn reduces the constriction of the urethra.  It can be done with a local anesthetic on an outpatient basis.  It takes about an hour to perform the procedure.  It takes about 30 days for the ablated prostate tissue to resorb.  Patients should have an annual rectal prostate exam for their doctor to feel the prostate health with a lubricated gloved finger.

Strictureplasty: Strictureplasty (also spelled Stricturoplasty) is a surgical procedure performed to alleviate bowel narrowing due to scar tissue that has built up in the intestinal wall from inflammatory bowel conditions such as Crohn’s disease.  The scar tissue accumulates as a result of repeated damage and healing, with the scarring causing a stricture (a narrowing of the lumen of the bowel).  The narrowing can force bowel contents into fissures and ulcers at the site, causing additional damage and narrowing.  The surgery restores free flow through the bowel without the need for removing bowel segments (i.e., without bowel resection).
