Question: At what age did Litto Nebbia write La balsa? Passage:"La balsa" (; Spanish for "the raft") is the debut single by the Argentine band Los Gatos, released on July 3, 1967 on Vik, a subsidiary of RCA Victor. Formed in 1967 after the disbandment of Los Gatos Salvajes, Los Gatos were the house band of the bar La Cueva, which became a popular meeting place for rock enthusiasts and the birthplace of Argentine rock—known locally as rock nacional (Spanish for "national rock"). During the mid-to-late 1960s, Buenos Aires was experiencing a cultural blossoming characterized by innovations in modern art, literature and cinema, largely driven by a burgeoning youth subculture that adhered to the countercultural phenomenon of the decade. The underground had its center in La Cueva, Plaza Francia and the Torcuato di Tella Institute, and identified with British Invasion music and the sexual revolution. "La balsa" was written by Litto Nebbia—lead vocalist of the band—and Tanguito (credited as Ramsés) on May 2, 1967, in the men's toilet of La Perla de Once, another bar frequented by the group. At the time, Argentina was under a military dictatorship led by Juan Carlos Onganía, which regularly imprisoned and persecuted these young bohemians.

Question: How long had the London Symphony Orchestra been playing for the year Matthews won the Ian Whyte Award? Passage:In 1975 his orchestral Fourth Sonata (written 1974–75) won the Scottish National Orchestra's Ian Whyte Award. Subsequent orchestral works include the widely performed Night Music (1976), Sonata No. 5: Landscape (1977–81), and a First Cello Concerto, commissioned by the BBC for the 1984 Proms: these last two have been recorded by Unicorn-Kanchana. In 1989 Cortège was given its first performance by the Orchestra of the Royal Opera House under Bernard Haitink, and Quatrain by the London Symphony Orchestra and Michael Tilson Thomas. This was the first of a series of LSO commissions, followed by Machines and Dreams for their 1991 Childhood Festival, Memorial in 1993 with Mstislav Rostropovich as conductor, and a Second Cello Concerto for Rostropovich in 1996. In 1990 he made a setting of three comic poems by Wendy Cope, Strugnell's Haiku. Matthews was Associate Composer with the LSO from 1992 until 1999. The orchestral version of Hidden Variables was a joint commission for the LSO and the New World Symphony Orchestra, who gave the American première in Miami under Michael Tilson Thomas in 1992; in the same year the Cleveland Orchestra gave the American première of Machines and Dreams. Collins Classics released a CD of Matthews' LSO commissions in 1996 to celebrate his 50th birthday.
