August 4, 1901 Louis Armstrong was born - an American trumpeter, composer, vocalist, and actor who was among the most influential figures in jazz. His career spanned five decades, from the 1920s to the 1960s, and different eras in the history of jazz.
June 27, 1970, a British rock band Queen was formed. Their classic line-up was Freddie Mercury (lead vocals, piano), Brian May (guitar, vocals), Roger Taylor (drums, vocals) and John Deacon (bass). Their earliest works were influenced by progressive rock, hard rock and heavy metal, but the band gradually ventured into more conventional and radio-friendly works by incorporating further styles, such as arena rock and pop rock.
