Question:
Rhapsody in Blue is a 1924 musical composition by American composer George Gershwin for solo piano and jazz band, which combines elements of classical music with jazz-influenced effects. Commissioned by bandleader Paul Whiteman, the composition was orchestrated by Ferde Grofe several times, including the original 1924 scoring, "theater orchestra" setting published in 1926, and the symphony orchestra scoring published in 1942, though completed earlier. The piece received its premiere in the concert, An Experiment in Modern Music, which was held on February 12, 1924, in Aeolian Hall, New York, by Whiteman and his band with Gershwin playing the piano. The editors of the Cambridge Music Handbooks opined that "The Rhapsody in Blue (1924) established Gershwin's reputation as a serious composer and has since become one of the most popular of all American concert works."
Rhapsody in Blue premiered in an afternoon concert on Tuesday, February 12, 1924, held by Paul Whiteman and his band Palais Royal Orchestra, entitled An Experiment in Modern Music, which took place in Aeolian Hall in New York City. Many important and influential composers of the time such as John Philip Sousa and Sergei Rachmaninoff were present. The event has since become historic specifically because of its premiere of the Rhapsody. The purpose of the experiment, as told by Whiteman in a pre-concert lecture in front of many classical music critics and highbrows, was "to be purely educational". It would "at least provide a stepping stone which will make it very simple for the masses to understand, and therefore, enjoy symphony and opera". The program was long, including 26 separate musical movements, divided into 2 parts and 11 sections, bearing titles such as "True form of jazz" and "Contrast: legitimate scoring vs. jazzing". Gershwin's latest composition was the second to last piece (before Elgar's Pomp and Circumstance March No. 1). Many of the numbers sounded similar and the ventilation system in the concert hall was broken. People in the audience were losing their patience, until the clarinet glissando that opened Rhapsody in Blue was heard. The Rhapsody was performed by Whiteman's band, with an added section of string players, and George Gershwin on piano. Gershwin decided to keep his options open as to when Whiteman would bring in the orchestra and he did not write down one of the pages for solo piano, with only the words "Wait for nod" scrawled by Grofe on the band score. Gershwin improvised some of what he was playing, and he did not write out the piano part until after the performance, so it is unknown exactly how the original Rhapsody sounded. The opening clarinet glissando came into being during rehearsal when; "... as a joke on Gershwin, [Ross] Gorman (Whiteman's virtuoso clarinettist) played the opening measure with a noticeable glissando, adding what he considered a humorous touch to the passage. Reacting favourably to Gorman's whimsy, Gershwin asked him to perform the opening measure that way at the concert and to add as much of a 'wail' as possible."

Question:
Joseph Patrick Kennedy Sr. (September 6, 1888 - November 18, 1969) was an American businessman, investor, and politician known for his high-profile positions in United States politics. Kennedy was married to Rose Kennedy, and three of their nine children attained distinguished political positions: President John F. Kennedy (1917-1963), Attorney General and Senator Robert F. Kennedy (1925-1968), and longtime Senator Edward M. "Ted" Kennedy (1932-2009). He was a leading member of the Democratic Party and of the Irish Catholic community.
Kennedy's close ties with Republican (GOP) Senator Joseph McCarthy strengthened his family's position among Irish Catholics, but weakened it among liberals who strongly opposed McCarthy. Even before McCarthy became famous in 1950, Kennedy had forged close ties with the Republican Senator. Kennedy often brought him to his family compound at Hyannis Port as a weekend house guest in the late 1940s. McCarthy at one point dated Patricia Kennedy. When McCarthy became a dominant voice of anti-Communism starting in 1950, Kennedy contributed thousands of dollars to McCarthy, and became one of his major supporters. In the Senate race of 1952, Kennedy apparently worked a deal so that McCarthy, a Republican, would not make campaign speeches for the GOP ticket in Massachusetts. In return, Congressman John F. Kennedy, running for the Senate seat, would not give any anti-McCarthy speeches that his liberal supporters wanted to hear. At Kennedy's urging in 1953, McCarthy hired Robert Kennedy (age 27) as a senior staff member of the Senate's investigations subcommittee, which McCarthy chaired. In 1954, when the Senate was threatening to condemn McCarthy, Senator John Kennedy faced a dilemma. "How could I demand that Joe McCarthy be censured for things he did when my own brother was on his staff?" asked JFK. By 1954 Robert F. Kennedy and McCarthy's chief aide Roy Cohn had had a falling out, and Robert no longer worked for McCarthy. John Kennedy had a speech drafted calling for the censure of McCarthy but he never delivered it. When the Senate voted to censure McCarthy on December 2, 1954, Senator Kennedy was in the hospital and never indicated how he would cast his vote. Joe Kennedy strongly supported McCarthy to the end.

Shashina had re-recorded Anastasia's recordings in the group's songs "Malo Tebya" and "Ugar", which is expected to release a video with Shashina featuring in it.

Serebro's 3rd studio album '925' was supposed to be released on iTunes Russia on 15 October 2015 but due to their studio harddrive being stolen, the album release had to be cancelled.
