Question: Who was tthe third of the "Three Kings of the Blues Guitar," besides Albert King and Freddie King?
Context: Freddie King (September 3, 1934 – December 28, 1976) was an American blues guitarist and singer.  He has been described as one of the "Three Kings" of electric blues guitar, along with Albert King and B.B. King.  He was an influential guitarist with hits for Federal Records in the early 1960s.  His soulful and powerful voice and distinctive guitar style inspired countless musicians, particularly guitarists (Eric Clapton is a notable example).  He was inducted into the Rock and Roll Hall of Fame in 2012. "The Stumble" is a blues guitar instrumental composed and recorded by American blues artist Freddie King, for his 1961 album "Let's Hide Away and Dance Away with Freddy King", (King 773).  It was released as the fourth single from this album in 1962.  It is considered a blues classic and follows in a string of popular instrumentals recorded by King in the early 1960s, including "Hide Away", "San-Ho-Zay", and "Sen-Sa-Shun". Benny Turner is an American blues musician.  He is the younger brother of Freddie King and was the bass guitarist for the Freddie King Band.  Later, Turner joined Mighty Joe Young as the bass guitarist of his band before becoming the bandleader for Marva Wright for 20 years.  Turner received the Independent Music Award for best blues song for "I Can't Leave" and his album "When She's Gone" was nominated for best traditional blues CD and best Soul Blues Album at the Blues Blast Awards in 2016. "Hide Away" or "Hideaway" is a blues guitar instrumental that has become "a standard for countless blues and rock musicians performing today".  First recorded in 1960 by Freddie King, the song became an R&B and pop chart hit.  Since then, it has been interpreted and recorded by numerous blues and other musicians and has been recognized by the Rock and Roll Hall of Fame and the Grammy Hall of Fame. "Born Under a Bad Sign" is a blues song recorded by American blues singer and guitarist Albert King in 1967.  Called "a timeless staple of the blues", the song also had strong crossover appeal to the rock audience with its bass and guitar harmony line and topical astrology reference.  "Born Under a Bad Sign" became an R&B chart hit for King and numerous blues and other musicians have made it perhaps the most recorded Albert King song. Selwyn Birchwood (born March 9, 1985) is an American blues guitarist, vocalist and songwriter from Tampa, Florida.  He was the winner of the Blues Foundation’s 2013 International Blues Challenge (band category), as well the winner of the Albert King Guitarist of the Year award, presented at the same event.  To win, he bested 125 other bands from around the world.  Birchwood plays electric guitar and electric lap steel guitar.  His live performances feature his original songs. " Living Blues" magazine said, "Selwyn Birchwood is making waves, surprising people and defying expectations.  Be on the lookout.  He revels in the unexpected." " The Tampa Tribune" said Birchwood plays with "power and precision reminiscent of blues guitar hero Buddy Guy.  He is a gritty vocalist [who is] commanding with his axe."  "Rolling Stone" said "Birchwood is a young, powerhouse guitarist and soulful vocalist.  "Don’t Call No Ambulance" is a remarkable debut by a major player."  "The Washington Post" said, "Selwyn Birchwood is an indelibly modern and original next-generation bluesman; his tough vocals, guitar and lap steel touch on classic Chicago blues, Southern soul and boogie." King of the Blues Guitar (Atlantic 8213) is a compilation album by blues guitarist and singer Albert King.  It was released by Atlantic Records in 1969 and re-released on CD format in 1989. The Big Blues is the debut album by Albert King, released in 1962 by King Records.  Featuring mostly songs composed by Albert King himself, this was his first album and the only one before he signed with Stax Records, where he would record most albums along his career. Little Freddie King (born Fread Eugene Martin, July 19, 1940) is an American Delta blues guitarist.  His style is based on that of Freddie King, but his approach to country blues is original. Albert Nelson (April 25, 1923 – December 21, 1992), known professionally as Albert King, was an American blues guitarist and singer whose playing influenced many other blues guitarists.  One of the "Three Kings of the Blues Guitar" (along with B.B. King and Freddie King), he is perhaps best known for the 1967 single "Born Under a Bad Sign".
