John Entwistle, English singer-songwriter, bass guitarist, and producer (b. 1944)
John Alec Entwistle (9 October 1944 – 27 June 2002) was an English musician and songwriter who was the bassist for the rock band The Who. Nicknamed "The Ox" and "Thunderfingers", Entwistle's music career spanned over four decades. He was the band's only member with formal musical training and also provided backing and occasional lead vocals. Entwistle was inducted into the Rock and Roll Hall of Fame as a member of the Who in 1990.
Renowned for his musical abilities, Entwistle's instrumental approach used pentatonic lead lines and a then-unusual treble-rich sound ("full treble, full volume"). He was voted as the greatest bassist of all time in a 2011 Rolling Stone readers' poll and named number seven by Bass Player in its "100 Greatest Bass Players" issue in 2017.
