Alcatrazz is an American rock band formed in 1983 by Graham Bonnet, Jimmy Waldo, and Gary Shea. They are best known for their songs "Island in the Sun", "Hiroshima Mon Amour", and "God Blessed Video". They are also notable for featuring a previously unknown Yngwie Malmsteen as their lead guitarist for a year, who was then replaced by Steve Vai, with whom they recorded one album.

Following an internal disagreement and split in 2020, there are currently two separate and distinct Alcatrazz line-ups, one featuring Bonnet, and another featuring Waldo and Shea.

The band went through a number of line-up changes, with Bonnet being the only member to be in every incarnation of Alcatrazz. Yngwie Malmsteen was the original guitarist of Alcatrazz from 1983 to 1984, and was subsequently replaced by Steve Vai, and then by Danny Johnson in the original incarnation of the band up until 1987. Joe Stump became the Alcatrazz guitarist when the band reformed, and remains the guitarist in the Waldo-Shea line-up of Alcatrazz. In June 2021, Jeff Loomis was announced as the guitarist in the Bonnet line-up of Alcatrazz.

After breaking up in 1987, Bonnet toured from 2006 to 2014 as Alcatrazz featuring Graham Bonnet with various line-ups, before a one-off reunion show in 2017 led to Bonnet and Waldo reforming the band once more in 2020, with Shea rejoining shortly after. From their inception in 1983 until 2020, Alcatrazz released four studio albums: No Parole from Rock 'n' Roll (1983), Disturbing the Peace (1985), Dangerous Games (1986), and Born Innocent (2020). Several months after the release of Born Innocent, Bonnet and the other four members of Alcatrazz – Waldo, Shea, Stump, and drummer Mark Benquechea – announced a split from one another, with both camps intending to continue to record music under the name Alcatrazz. The Waldo-Shea-Stump-Benquechea camp announced that Doogie White was now their lead singer, and released the studio album V in October 2021. Meanwhile, Bonnet announced that he was moving forward once again with his own version of Alcatrazz. In June 2021, Jeff Loomis was announced as the guitarist for the Bonnet line-up of Alcatrazz, with a new studio album in the works.

The band's initial line-up consisted of former Rainbow singer frontman Graham Bonnet, young Swedish guitarist Yngwie Malmsteen, who had recently left the American metal band Steeler, Gary Shea and Jimmy Waldo from New England and Clive Burr of Iron Maiden fame. Burr was reportedly only in the band for a week, and left upon discovering the band was going to be based in the United States, as opposed to his native England. Burr was soon replaced by former Iron Butterfly drummer Jan Uvena, who had just left Alice Cooper's backing band. Shea dubbed the group "Alcatrazz". For the first album, the bulk of the material was written by Bonnet and Malmsteen, with Waldo contributing to several tracks.

The band's debut album, No Parole from Rock 'n' Roll was released in late 1983 on Rocshire Records. Decent support was given by MTV to the lead single, "Island in the Sun", which showed a heavy Rainbow influence. Despite the commercial nature of the song, it received little radio play. The album nonetheless spent 18 weeks on the Billboard charts and peaked at No. 128. A second video released in 1984 for "Hiroshima Mon Amour" became popular in Japan.

Rochsire then released Live Sentence (1984), a concert recording with songs from both concerts of the recent tour of Japan at the Nakano Sun Plaza in Tokyo on January 28, 1984. Being discontent with the sonic qualities of the recording, Malmsteen tried to prevent the release of the album but failed. Some Rainbow covers were included, including "Since You Been Gone". The album peaked at No. 133 in the US. A live video concert was also produced. During this period, internal turmoil began surfacing within the band, between Malmsteen and Bonnet. According to Malmsteen, Bonnet had become fed up with the attention drawn to his guitar playing from fans over Bonnet's vocals. According to Malmsteen, their professional relationship ended with the two having an altercation on stage after Bonnet allegedly tampered with Malmsteen's amplifiers during a guitar solo and "Since You Been Gone" at a show in Oklahoma. This resulted in Malmsteen yelling at and arguing with Bonnet, Bonnet poking Malmsteen in the stomach with his microphone stand, and finally with Malmsteen punching Bonnet, all taking place on stage. Following this, Malmsteen left Alcatrazz and created his own band called Rising Force, who signed with Polydor Records and released a successful self-titled debut album.

Waldo replaced Malmsteen with former Frank Zappa guitarist Steve Vai, despite resistance from Bonnet, and the band signed with Capitol Records after Rocshire was shut down following the owners being arrested for the embezzlement of millions of dollars. With Steve Vai, the group worked on new material and then headlined another tour of Japan, which introduced Vai to the fans and allowed them to play new material from the upcoming album. A concert video was filmed from these dates.
