Problem: Bloc Party are an English rock band, currently composed of Kele Okereke (lead vocals, rhythm guitar, keyboards, sampler), Russell Lissack (lead guitar, keyboards), Justin Harris (bass guitar, keyboards, saxophones, backing vocals) and Louise Bartle (drums, percussion). Former members Matt Tong and Gordon Moakes left the band in 2013 and 2015 respectively. Their brand of music, whilst rooted in rock, retains elements of other genres such as electronica and house music. The band was formed at the 1999 Reading Festival by Okereke and Lissack.

Bloc Party's second album, A Weekend in the City, was produced by Garret "Jacknife" Lee. It was released in February 2007, although it was leaked in November 2006. It became available for download on the UK iTunes Store before the physical release, and reached the number 2 spot on the UK Albums Chart. The album also reached number 2 on the Australian and Belgian charts, and debuted at number 12 in the Billboard 200, with 48,000 copies sold. The first single, "The Prayer", was released on 29 January, and became the band's highest charting single in the British Top 40, reaching number 4. In the buildup to the release of the album, BBC Radio 1 DJ Zane Lowe aired a live set by the band from Maida Vale studios on 30 January 2007, featuring a mix of old and new songs. On 1 February 2007, A Weekend in the City was made available to listen to for free through Bloc Party's official MySpace page. The next single, "I Still Remember", was Bloc Party's highest charting American single, peaking at number 24 on the Modern Rock Chart. The band released their third single, "Hunting for Witches", with an accompanying video clip in August 2007. The single became their only ARIA Chart entry, peaking at number 20. In October 2007, it was announced that Bloc Party would release a new single, "Flux", on 13 November--ahead of their end of year gigs. The electronic song, also produced by Jacknife Lee, was very different from previous singles released by the band. The band's first gig following the release of A Weekend in the City was on 5 February 2007, in Reading, and was broadcast live on BBC 6 Music. On 20 May 2007, Bloc Party headlined on the In New Music We Trust stage at the BBC Radio 1 Big Weekend in Preston. They also performed at the UK leg of Live Earth on 7 July 2007 at Wembley Stadium. Furthermore, the band played sets at T in the Park and Oxegen 07 that same weekend, as well as Glastonbury and the Reading and Leeds Festivals later in 2007. Bloc Party announced a tour of Australia and New Zealand in August 2007, which would include a special appearance at the Splendour in the Grass Festival on 5 August. On 17 September 2007, they recorded a set for the PBS show Austin City Limits a day after playing at the Austin City Limits Music Festival. On 27 October, the band performed a set at London's The Roundhouse with the Exmoor Singers, a London-based choir, as part of the BBC Electric Proms. The set included songs from both Silent Alarm and A Weekend in the City along with the first British live performance of "Flux".

Question:
Journey is an American rock band that formed in San Francisco in 1973, composed of former members of Santana and Frumious Bandersnatch. The band has gone through several phases; its strongest commercial success occurred between 1978 and 1987. During that period, the band released a series of hit songs, including "Don't Stop Believin'" (1981), which in 2009 became the top-selling track in iTunes history among songs not released in the 21st century. Its parent studio album, Escape, the band's eighth and most successful, reached No. 1 on the Billboard 200 and yielded another of their most popular singles, "Open Arms".
Journey's album sales did not improve and Columbia Records requested that they change their musical style and add a frontman, with whom keyboardist Gregg Rolie could share lead vocal duties. The band hired Robert Fleischman and transitioned to a more popular style, akin to that of Foreigner and Boston. Journey went on tour with Fleischman in 1977 and together the new incarnation of the band wrote the hit "Wheel in the Sky"; however, management differences resulted in Fleischman leaving within the year. In late 1977, Journey hired Steve Perry as their new lead singer. Herbie Herbert, the band's manager, also hired Roy Thomas Baker as a producer to add a layered sound approach as Baker had done with his previous band, Queen. With their new lead singer and talented new producer, Journey released their fourth album, Infinity (1978). This album set Journey on their road to stardom with their first RIAA-certified platinum album. This album, with their hit song "Wheel in the Sky" (#57 U.S.), set Journey on a new path with a more mainstream sound to make their highest chart success to date. In late 1978, manager Herbie Herbert fired drummer Aynsley Dunbar, who joined Bay Area rivals Jefferson Starship shortly thereafter. He was replaced by Berklee-trained jazz drummer Steve Smith. Perry, Schon, Rolie, Smith and Valory recorded Evolution (1979), which gave the band their first Billboard Hot 100 Top 20 single, "Lovin', Touchin', Squeezin'" (#16); and Departure (1980), which reached No. 8 on the album charts. Journey's newfound success brought the band an almost entirely new fan base. During the 1980 Departure world tour, the band recorded a live album, Captured. Keyboardist Gregg Rolie then left the band, the second time in his career he left a successful act. Keyboardist Stevie "Keys" Roseman was brought in to record the lone studio track for Captured, "The Party's Over (Hopelessly in Love)," but Rolie recommended pianist Jonathan Cain of The Babys as the permanent replacement. With Cain's replacement of Rolie's Hammond B-3 organ with his own synthesizers, the band was poised for a new decade in which they would achieve their greatest musical success.
