Context: Bluefinger is an album by Black Francis (a.k.a. Frank Black).  The album was released on 11 September 2007 in the United States and Europe.  The project was revealed via several cryptic posts by Black on his unofficial website, which were confirmed as accurate when the album leaked to file-sharing services earlier in the year. Mark Linkous (September 9, 1962 – March 6, 2010) was an American singer, songwriter and musician, best known as leader of Sparklehorse.  He was also known for his collaborations with such notable artists as Tom Waits, PJ Harvey, Daniel Johnston, Radiohead, Black Francis, Julian Casablancas, Nina Persson, David Lynch, Fennesz, Danger Mouse, and Sage Francis. Paley & Francis is a studio album by Paley & Francis (Reid Paley and Black Francis), recorded in Nashville in September 2010, and released in the UK & Europe on October 10, 2011 on Cooking Vinyl, and in North America on October 11, 2011 on Sonic Unyon. "Crackity Jones" is an alternative rock song by the American band Pixies, and is the ninth track on their 1989 album "Doolittle".  Written and sung by the band's frontman Black Francis, "Crackity Jones" describes a crazed roommate and was inspired by Francis' stay in an apartment block with a "weirdo, psycho, gay roommate" in Puerto Rico as a student. Charles Michael Kittridge Thompson IV (born April 6, 1965) is an American singer, songwriter and guitarist.  He is best known as the frontman of the influential alternative rock band Pixies, with whom he performs under the stage name Black Francis.  Following the band's breakup in 1993, he embarked on a solo career under the name Frank Black.  After releasing two albums with record label 4AD and one with American Recordings, he left the label and formed a new band, Frank Black and the Catholics.  He re-adopted the name Black Francis in 2007. Makoto Koshinaka (越中睦 / 越中睦士 or Makoto, born July 15, 1980 in Moto Azabu, Tokyo) is a Japanese singer, songwriter, actor and model, activating both in Japan and in Thailand, starting with the year 1999.  His musical career covers various musical styles (from pop rock, folk rock, solo – as Makoto, and with the visual kei bands Λucifer and †яi￠к, under the agencies Unlimited Records, BM Factory, Crown Records, T.N.B and, currently, SCSC Records) and his acting career covers roles in stage plays, TV dramas and feature movies. Todd O'Keefe (Born November 10, 1972) is an American singer-songwriter, guitarist and bass player.  Artists O'Keefe has worked with include The 88, Ray Davies, Black Francis, Jeff Beck, Elvis Costello and Rusty Anderson.  O'Keefe contributed background vocals to Social Distortion's 2010 release "Hard Times and Nursery Rhymes".  He sang on The Posies 2016 album Solid States.  He was the singer and guitarist for Los Angeles pop rock band The Green and Yellow TV. "Letter to Memphis" is a single by the alternative rock band Pixies on the album "Trompe le Monde".  The song has been described as a melancholy love song about a letter lead singer Black Francis failed to write.  "Letter to Memphis" has been commended for being a song that "sticks in your mind", specifically the lyric "Trying to get to you."  The song is supposed to be Francis' take on Chuck Berry's song "Memphis, Tennessee."  An instrumental version was included as a B-side to "Alec Eiffel" and later became the closing track of their compilation "Complete 'B' Sides". The Cult of Ray is a 1996 album by Frank Black (also known as Black Francis.)  It is his third solo album released after the initial breakup of The Pixies.  Unlike his previous two albums, which had been produced by former Pere Ubu keyboardist Eric Drew Feldman, Black opted to produce this one himself. Frank Black Francis is a 2-CD set released in 2004 by Frank Black, roughly coinciding with the Pixies reunion tour.  Disc 1 consists of a March 1987 solo acoustic demo tape recorded by engineer Gary Smith, just prior to the first Pixies recording session.  Disc 2 is a contemporary recording of Frank Black reworking a number of Pixies songs with Keith Moliné and Andy Diagram, who are part of David Thomas and Two Pale Boys.
