Question: Billy Milano is the vocalist of a band formed in which city ?

Context paragraphs:
20 Years of Dysfunction: 20 Years Of Dysfunction is a DVD/CD released in 2005 by crossover thrash band Stormtroopers Of Death.  Mainly created by singer Billy Milano, the material for the 2-disc DVD/CD is mostly culled from fan-shot amateur footage.  The relative scarceness of available material has resulted in some hilarious decisions by the production team; for instance, "Milk" is sung by Danny Lilker but the video footage inappropriately shows vocalist Milano singing.  Also notable is that the DVD does not include any material from the second Stormtroopers Of Death studio album "Bigger Than The Devil".

Thrash of the Titans: Thrash of the Titans was a benefit concert held on August 11, 2001 at the Maritime Hall in San Francisco, CA.  The concert was a co-benefit for Testament vocalist Chuck Billy, who was diagnosed with germ cell seminoma (a rare form of cancer); and Chuck Schuldiner, leader of the death metal band Death, who was also battling cancer.  The Master of Ceremonies for the evening was S.O.D. vocalist Billy Milano.  The concert was organized by Walter Morgan.  The show was announced in May 2001, and all 2300 tickets quickly sold out.

Biohazard (band): Biohazard is an American heavy metal band formed in Brooklyn, New York in 1987.  They are acknowledged as one of the earliest bands to fuse hardcore punk and heavy metal with elements of hip hop.  The earliest lineup consisted of bassist/vocalist Evan Seinfeld, guitarist Bobby Hambel, and drummer Anthony Meo.  Guitarist/vocalist Billy Graziadei would join the band soon after, changing the band to a four-piece.  Since February 2016, the lineup has consisted of Billy Graziadei, Bobby Hambel and Danny Schuler.

Billy Milano: Billy Milano is a Bronx-born heavy metal musician now based in Austin, Texas.  He is the singer and - occasionally - guitarist and bassist of crossover thrash band M.O.D., and he was also the singer of its predecessor, Stormtroopers of Death.  He was also the singer of United Forces, which also featured his Stormtroopers of Death bandmate Dan Lilker.

Buffalo (band): Buffalo was an Australian rock band formed in August 1971 by founding mainstay Dave Tice on lead vocals (ex-Head).  Fellow founders, also from Head, were Paul Balbi on drums, John Baxter on guitar, and Peter Wells on bass guitar; together with Alan Milano on lead vocals (ex-Mandala).  Milano left after their debut album, "Dead Forever..." (June 1972), and Balbi was replaced on drums by Jimmy Economou.  Their next two albums, "Volcanic Rock" (July 1973) and "Only Want You For Your Body" (June 1974), were also issued by Vertigo Records.  After 1975 line-up changes resulted in a more commercial sound and the group disbanded in March 1977.  Australian musicologist Ian McFarlane noted that there was "nothing subtle about Buffalo's primal, heavyweight sound, but it was delivered with a great deal of conviction ... combining the dense, occult riffing ... with the progressive blues chops ... the band certainly captured the arrogant disposition of the times in a bold and thunderous fashion".  Alongside Billy Thorpe & The Aztecs and Blackfeather, Buffalo pioneered Australia's heavy metal, pub rock and alternative rock movements.  Peter Wells died on 27 March 2006, aged 58.

Dan Lilker: Daniel A. "Dan" Lilker (born October 18, 1964 in Bayside, New York) is a musician from the United States, most known as a bass player, but also guitarist, pianist, drummer and vocalist.  He is the bassist for the thrash metal band Nuclear Assault and was a founding member of Anthrax with Scott Ian, (Lilker was then playing rhythm guitar) and recorded bass guitar and co-wrote on their first album, "Fistful of Metal".  He also founded crossover band Stormtroopers of Death with Scott Ian and Charlie Benante (from Anthrax), and Billy Milano (Anthrax roadie, M.O.D. singer).  He also plays bass with Brutal Truth, Exit-13, Malformed Earthborn, The Ravenous, Overlord Exterminator, Venomous Concept, Crucifist, Nokturnal Hellstorm and Extra Hot Sauce.

Something's Gotta Give (album): Something's Gotta Give is the fifth full-length studio album by New York hardcore band, Agnostic Front.  It was released in June 1998 on Epitaph Records and follows 1995's "Raw Unleashed" compilation album.  It is actually the first studio album since 1992's "One Voice".  The album was co-produced by Billy Milano, the frontman of crossover thrash bands S.O.D. and M.O.D..  It marks a return to a more hardcore punk style of sound than the thrash metal inspired music of "One Voice".  Backing vocals, amongst others, were provided by Tim Armstrong and Lars Frederiksen of Rancid, and Jimmy Gestapo of Murphy's Law.

M.O.D.: M.O.D. (abbreviation for Method of Destruction) is a crossover thrash band from New York City, fronted by Stormtroopers of Death vocalist Billy Milano.  The band has been around for 31 years (minus one hiatus from 1997 to 2001), and released eight studio albums.  With M.O.D., Milano sought to continue on the musical path of the bands Anthrax, Stormtroopers of Death and Nuclear Assault, mixing shades of hardcore punk with thrash metal and often humorous and politically incorrect lyrics.

Zoetrope (band): Zoetrope was an American heavy metal band from Chicago, Illinois.  Although their sound was akin to thrash metal, the group described themselves as "Street Metal".  The group was formed in 1976 by teenage friends Barry Stern (drums/vocals), Kevin Michael Rasofsky, aka Kevin Michael, (guitar), and Calvin "Willis" Humphrey (bass), soon to be joined by second guitarist Ken Black.  Initially playing covers, the band soon ventured into writing their own material and released a single in 1980.  Although undeniably a metal band, Zoetrope was also active in Chicago's hardcore punk scene, sharing bills with locals hardcore bands and hanging out at O'Banions, a Chicago punk bar (Ken Black and Barry Stern also produced the self-titled LP by Chicago-based hardcore band Life Sentence in 1986).  Following the release of a couple of demo tapes, the group was signed to Combat Records and issued their first LP, "Amnesty", in 1985.  In 1987, the band traveled to Los Angeles to record their follow up, "A Life of Crime", with producer Randy Burns (Megadeth, Nuclear Assault).  During the recording sessions, Ken Black left the band and returned to Chicago to sort out substance abuse issues.  He was replaced by Louis Svitek.  Although Svitek appears on the album's cover, Kevin Michael later confirmed that Ken Black had finished his guitar parts before leaving Los Angeles.  During the tour supporting "A Life of Crime", Svitek was recruited for M.O.D. by Billy Milano.  After the tour, Barry Stern jumped ship to fellow Chicagoans Trouble.  Kevin Michael eventually returned with a new line up for 1993's "Mind Over Splatter" but the band folded for good soon after.

Stormtroopers of Death: Stormtroopers of Death (also known as S.O.D.) were an American crossover thrash band formed in New York City in 1985.

The band is also known for reuniting Anthrax members Scott Ian (guitars) and Charlie Benante (drums) with their former bassist Dan Lilker.  The song "Milano Mosh" from their 1985 debut album, "Speak English or Die", was the "Headbanger's Ball" intro anthem for many years.
