Question: Ike Turner worked with which famous American Chicago blues and electric blues pianist and organist? 
Context: Electric blues refers to any type of blues music distinguished by the use of electric amplification for musical instruments.  The guitar was the first instrument to be popularly amplified and used by early pioneers T-Bone Walker in the late 1930s and John Lee Hooker and Muddy Waters in the 1940s.  Their styles developed into West Coast blues, Detroit blues, and post-World War II Chicago blues, which differed from earlier, predominantly acoustic-style blues.  By the early 1950s, Little Walter was a featured soloist on blues harmonica or blues harp using a small hand-held microphone fed into a guitar amplifier.  Although it took a little longer, the electric bass guitar gradually replaced the stand-up bass by the early 1960s.  Electric organs and especially keyboards later became widely used in electric blues. The electric blues is a type of blues music distinguished by the amplification of the guitar, the bass guitar, and/or the harmonica and other instruments.  Electric blues is performed in several regional subgenres, such as Chicago blues, Texas blues, Delta blues and Memphis blues.  Though most interpretations of electric blues have a solemn tone through the common uses of the minor pentatonic scale, slow backing, and extended soloing periods, that extend through all subgenres.  The following is a list of electric blues musicians. Barrelhouse Chuck (born Harvey Charles Goering; July 10, 1958 – December 12, 2016) was an American Chicago blues and electric blues pianist, keyboardist, singer, and songwriter. The Chicago blues is a form of blues music indigenous to Chicago, Illinois.  Chicago blues is an electric blues style of urban blues.  Urban blues evolved from classic blues following the Great Migration, or the Great Northern Drive, which was both forced and voluntary at times, of African Americans from the southern United States to the industrial cities of the north, such as Chicago.  Muddy Waters directly joined that migration, like many others, such as in Florida, avoiding the more harshly southern Jim Crow laws.  Bruce Iglauer, founder of Alligator Records stated that, "Chicago blues is the music of the industrial city, and has an industrial sense about it."  Additionally, recognizing the shift in blues, Chicago blues singer and guitarist Kevin Moore expressed the blues transition stating, "You have to put some new life into it, new blood, new perspectives.  You can't keep talking about mules, workin' on the levee." Johnny "Big Moose" Walker (June 27, 1927 November 27, 1999) was an American Chicago blues and electric blues pianist and organist.  He worked with many blues musicians, including Ike Turner, Sonny Boy Williamson II, Lowell Fulson, Choker Campbell, Elmore James, Earl Hooker, Muddy Waters, Otis Spann, Sunnyland Slim, Jimmy Dawkins and Son Seals. Izear Luster "Ike" Turner, Jr. (November 5, 1931 – December 12, 2007) was an American musician, bandleader, songwriter, arranger, talent scout, and record producer.  An early pioneer of fifties rock and roll, he is most popularly known for his work in the 1960s and 1970s with his then-wife Tina Turner in the Ike & Tina Turner Revue. Nick Moss (born December 15, 1969, Chicago, Illinois, United States) is an American Chicago blues and electric blues musician.  He has released ten albums to date, all on his own label, Blue Bella Records label.  He has played with Buddy Scott, Jimmy Dawkins, Jimmy Rogers and the Legendary Blues Band.  More recently he has performed fronting his own group, Nick Moss and the Flip Tops until 2008 and then shortening the name in 2009 to Nick Moss Band.  The music journalist Bill Dahl stated that Moss possesses "mastery of the classic Chicago sound." James Henry Dawkins (October 24, 1936 – April 10, 2013) was an American Chicago blues and electric blues guitarist and singer.  He is generally considered to have been a practitioner of the "West Side sound" of Chicago blues. Johnny B. Moore (born Johnny Belle Moore, January 24, 1950, Clarksdale, Mississippi) is an American Chicago blues and electric blues guitarist, singer and songwriter.  He was a member of Koko Taylor's backing band in the mid-1970s.  He has recorded nine solo albums since 1987.  Moore's music retains a link to the earlier Chicago blues of Jimmy Reed and Muddy Waters, who also travelled to Chicago from the Mississippi Delta. Jimmie Gordon was an American Chicago blues pianist, singer, and songwriter.  In the course of his career he accompanied Memphis Minnie, Bumble Bee Slim, and Big Bill Broonzy, amongst others.  He had a hit with "I'd Rather Drink Muddy Water" (1936) and was active on the Chicago blues scene for a number of years leading up to World War II.  He is known to have recorded 67 tracks between 1934 and 1946.  Gordon was a mainstay of Decca Records during the 1930s and early 1940s, with his recorded work utilizing a piano accompaniment (often his own), as well as guitar, or with a small band that he assembled for the work.
