Background: Wladyslaw Gomulka (Polish: [vwa'diswaf go'muwka]; 6 February 1905 - 1 September 1982) was a Polish communist politician. He was the de facto leader of post-war Poland until 1948. Following the Polish October he became leader again from 1956 to 1970. Gomulka was initially very popular for his reforms; his seeking a "Polish way to socialism"; and giving rise to the period known as "Gomulka's thaw".
Context: In the fall of 1943, the PPR leadership began discussing the creation of a Polish quasi-parliamentary, communist-led body, to be named the State National Council (Krajowa Rada Narodowa, KRN). After the Battle of Kursk the expectation was of a Soviet victory and liberation of Poland and the PPR wanted to be ready to assume power. Gomulka came up with the idea of a national council and imposed his point of view on the rest of the leadership. The PPR intended to obtain consent from the Cominterm leader and their Soviet contact Georgi Dimitrov. However, in November the Gestapo arrested Finder and Malgorzata Fornalska, who possessed the secret codes for communication with Moscow and the Soviet response remained unknown. In the absence of Finder, on 23 November Gomulka was elected general secretary (chief) of the PPR and Bierut joined the three-person inner leadership. The founding meeting of the State National Council took place in the late evening of 31 December 1943. The new body's chairman Bierut was becoming Gomulka's main rival. In mid-January 1944 Dimitrov was finally informed of the KRN's existence, which surprised both him and the Polish communist leaders in Moscow, increasingly led by Jakub Berman, who had other, competing ideas concerning the establishment of a Polish communist ruling party and government. Gomulka felt that the Polish communists in occupied Poland had a better understanding of Polish realities than their brethren in Moscow and that the State National Council should determine the shape of the future executive government of Poland. Nevertheless, to gain a Soviet approval and to clear any misunderstandings a KRN delegation left Warsaw in mid-March heading for Moscow, where it arrived two months later. By that time Stalin concluded that the existence of the KRN was a positive development and the Poles arriving from Warsaw were received and greeted by him and other Soviet dignitaries. The Union of Polish Patriots and the Central Bureau of Polish Communists in Moscow were now under pressure to recognize the primacy of the PPR, the KRN and Wladyslaw Gomulka, which they ultimately did only in mid-July. On 20 July, the Soviet forces under Marshal Konstantin Rokossovsky forced their way across the Bug River and on that same day the combined meeting of Polish communists from the Moscow and Warsaw factions finalized the arrangements regarding the establishment (on 21 July) of the Polish Committee of National Liberation (PKWN), a temporary government headed by Edward Osobka-Morawski, a socialist allied with the communists. Gomulka and other PPR leaders left Warsaw and headed for the Soviet-controlled territory, arriving in Lublin on 1 August, the day the Warsaw Uprising erupted in the Polish capital.

Background: Weather Report was an American jazz fusion band of the 1970s and early 1980s. The band was initially co-led by the Austrian-born keyboard player Joe Zawinul, the American saxophonist Wayne Shorter and Czech bassist Miroslav Vitous. Due to creative and financial disagreements, Vitous left the band after a few years. Zawinul took increasing control and steered the band towards a more funk, R&B oriented sound.
Context: 1976's Black Market album was perhaps the most rock-oriented work which the group had produced to date. Weather Report's music had evolved further from open-ended funk jams into more melody-oriented, concise forms, which also offered a greater mass-market appeal. Zawinul further consolidated his use of keyboard synthesizers, while Shorter experimented with an early form of wind synthesizer, the Lyricon. However, the album was recorded during yet another period of change for the group, with multiple personnel shuffles. Although Alyrio Lima played percussion on one track, he was replaced during the sessions by Don Alias (his first appearance with the group since the debut album debacle) and by Alex Acuna (a Peruvian drummer and conga player based in Las Vegas, who had played with Elvis Presley and Ike Turner, among others). Alphonso Johnson was also worn out from the strain put on the rhythm by the band's frequent changes of drummer. During a break in activity halfway through the recording of Black Market, Johnson opted to leave Weather Report to play with the Billy Cobham/George Duke Band (which featured a young John Scofield on guitar). Prior to his departure, Johnson played on all but two of the new album's tracks. His replacement was Jaco Pastorius, a virtuoso fretless bass guitarist from Florida, who had been in touch with Zawinul for several years, and who came in to play on "Cannon Ball" and his own composition "Barbary Coast". Zawinul and Shorter had assumed that Chester Thompson would be departing alongside his friend Johnson, and for the second set of sessions they replaced him (on Jaco Pastorius' recommendation) with the former Mahavishnu Orchestra drummer Narada Michael Walden. Although Walden played on several album tracks, he ultimately proved unsuitable. Thompson returned for the final Black Market sessions, but left again after failing to gel as a rhythm section with Pastorius (whose style was much busier than that of Johnson). Thompson subsequently joined Genesis as their touring drummer. Black Market continued Weather Report's ongoing run of success, selling well and being the fourth of the band's albums to win the album of the year award from Down Beat magazine. For the subsequent tour, Alex Acuna moved from percussion to the drum kit, and Don Alias was replaced by the young Puerto Rican percussionist Manolo Badrena, who had previously played with various Latin rock bands and with Art Blakey. The band made a very well-received appearance at the Montreux Jazz Festival, which was filmed for future release.
