Background: Titas (Portuguese pronunciation: [tSi'tas]) are a rock band from Sao Paulo, Brazil. Though they basically play pop/alternative rock, their music has touched a number of other styles throughout their 30-year career, such as new wave, punk rock, grunge, MPB and electronic music. They are one of the most successful rock bands in Brazil, having sold more than 6,3 million albums as of 2005 and having been covered by several well-known Brazilian artists and a couple of international singers. They were awarded a Latin Grammy in 2009 and have won the Imprensa Trophy for Best Band a record four times.
Context: The band hired the bass guitarist Lee Marcucci (from Radio Taxi) to play in their album Como Estao Voces? (How Are You?). As this album was released, the five remaining members continued to write the history of more than 20 years of the band. With self-help hits as "Enquanto Houver Sol", questions on relevance remain on Titas' side, which faced declining sales and the ageing of their fanbase.  In 2005, they released another MTV-branded album, only this time in a non-acoustic live performance. This album generated a new hit for the group, called "Vossa Excelencia", that basically criticizes the hypocrisy and lack of care from politicians, thus bringing the band back to its roots. It was seen as another opportunistic stunt by Brazilian critics, as the song was released exactly when Lula's government was facing manifold accusations of corruption.  On February 18, 2006, Titas opened the Rolling Stones free concert at Copacabana beach, Rio de Janeiro for an audience of some 1.5 million people.  In 2007, the band started a tour, entitled 25 Anos de Rock (25 Years of Rock), joining Os Paralamas do Sucesso to celebrate the 25th anniversary of both bands, as well as the 25th anniversary of the rising of 1980s Brazilian rock bands. The two line-ups played together most of the time on the shows, presenting also some invited musicians, like Arnaldo Antunes, Andreas Kisser and Dado Villa-Lobos. The concert in Rio de Janeiro, which took place at January 26, 2008, was recorded and filmed. The resulting CD and DVD from the show were released five months after.

Problem: 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.
