Michael "Jakko" Jakszyk (born Michael Lee Curran, 8 June 1958) is an English musician, record producer, and actor. He has released several solo albums as a singer, songwriter, and multi-instrumentalist and has been the lead singer for King Crimson since 2013. His work has been variously credited to "Jakko", "Jakko Jakszyk", and "Jakko M. Jakszyk". Before joining King Crimson, he led bands for over thirty years, including 64 Spoons, Dizrhythmia, 21st Century Schizoid Band, Jakszyk Fripp Collins, and Rapid Eye Movement.

By 1975, Jakszyk was leading an eccentric jazz-rock band called Soon After. His self-confessed "dictatorial tendencies" reduced a bigger line-up to a trio of "two screaming lead guitars and a trumpet" (the latter played by ex-National Youth Jazz Orchestra member Ted Emmett). The band reached the finals of the 1975 Melody Maker National Rock/Folk competition, finishing third to a heavy metal band featuring future Clash co-leader Mick Jones and to a big band featuring future saxophone session musician Gary Barnacle. When Soon After split up, Jakszyk toured with "a strange little band" which supported Camel, Stackridge, and Judas Priest, then briefly joined a Tring-based band called Synthesis which played progressive rock in the Canterbury-scene vein.  Jakszyk's first significant band was 64 Spoons, which he joined as guitarist and lead singer in 1976, co-writing much of the band's material. Between 1976 and 1980, 64 Spoons wrote and performed a blend of pop, progressive rock, jazz, and comedy (typified by their single "Ladies Don't Have Willies"). Boosted by an exuberant and funny live show, 64 Spoons proved popular with audiences but failed to gain an effective record deal or media breakthrough and split up in 1980. Their only album, Landing on a Rat Column, was eventually released in 1992, many years after it was recorded. Jakszyk would described them as "the wrong band at the wrong time".  64 Spoons's work did, however, lead to friendships with several of the musicians who had inspired the band, notably keyboard player Dave Stewart. Following the split of 64 Spoons, Jakszyk joined Stewart, Rick Biddulph, and Pip Pyle in the band Rapid Eye Movement. Jakszyk contributed several songs to the band's repertoire ("One More Time", "I'll Stand On My Own", "Ingmar Bergman on the Window Sill", "Straining Our Eyes", and "Dear Clare", the last of these a 64 Spoons song) and co-wrote material with Stewart ("This Is Not What I Want" and "'Allo Darlin' I Work on the Fair"). Between August 1980 and June 1981, Rapid Eye Movement toured Spain, France, and the UK and recorded material but split up due to Stewart's desire to concentrate on studio work (Jakszyk sang on the original version of Stewart's cover of "What Becomes of the Brokenhearted?", later a hit with a new vocal track by the Zombies' lead singer Colin Blunstone).  During this period, Jakszyk also contributed to sessions for the former Van der Graaf Generator saxophonist David Jackson's album The Long Hello Vol. 3 (eventually released in 1982).
