Question: Who was the fingerstyle guitarist that Kevin Kelley played drums for as a session musician?
Context: Adam Hamilton is a Los Angeles-based music producer, songwriter, and session musician.  Hamilton was the bass guitarist of glam metal band L.A. Guns from 2001 through 2007.  He also played drums for 1990s alternative rock band Joe 90, and worked as session drummer for alternative/neo-psychedelic band The Brian Jonestown Massacre.  Hamilton is a multi-instrumentalist who plays guitar, bass guitar, keyboards, and drums. Kevin Daniel Kelley (March 25, 1943 – April 6, 2002) was an American drummer, best known for his work with the rock bands The Byrds and the Rising Sons.  Kelley also played drums for Fever Tree, although it is unknown whether he was an official member of the group or not.  In addition, he worked as a session musician between 1969 and 1973, playing drums on albums by artists including John Fahey and Phil Ochs.  He appears to have retired from the music industry after drumming on Michael Cohen's 1973 album, "What Did You Expect?"  Kelley is the cousin of country rock pioneer and ex-member of The Byrds and The Flying Burrito Brothers, Chris Hillman.  Kevin Kelley should not be confused with the similarly named Kevin Kelly, another American session musician who played piano for Joan Baez during the Rolling Thunder Revue and guested on albums by Tim Buckley, Judee Sill, Bryn Haworth, and The Babys during the 1970s. Edgar Cruz is an independent classical and fingerstyle guitarist from Oklahoma City, Oklahoma.  Having recorded over a sixteen CDs in styles ranging from classical to flamenco to pop to jazz, Cruz is perhaps best known for his fingerstyle arrangement of Queen's "Bohemian Rhapsody".  Additionally, Cruz was featured in an OETA (Oklahoma's PBS affiliate) documentary entitled "Spanish Blood - The Guitar of Edgar Cruz".  Cruz took second place in the 1991 Walnut Valley Festival in Winfield, Kansas in the fingerstyle competition as did his brother Mark Anthony Cruz in 1993 & 2001.  Cruz's career began when he followed in his father Manuel Cruz' footsteps playing for restaurant customers as a strolling guitarist.  His marketing strategy was taken from his father who said, "play what your audience wants and they'll pay you well". John Aloysius Fahey (February 28, 1939 – February 22, 2001) was an American fingerstyle guitarist and composer who played the steel-string acoustic guitar as a solo instrument.  His style has been greatly influential and has been described as the foundation of American Primitive Guitar, a term borrowed from painting and referring mainly to the self-taught nature of the music and its minimalist style.  Fahey borrowed from the folk and blues traditions in American roots music, having compiled many forgotten early recordings in these genres.  He would later incorporate classical, Portuguese, Brazilian, and Indian music into his œuvre.  He spent many of his later years in poverty and poor health, but enjoyed a minor career resurgence with a turn towards the more explicitly avant-garde, and created a series of abstract paintings during the last years of his life.  He died in 2001 from complications from heart surgery.  In 2003, he was ranked 35th in the "Rolling Stone" "The 100 Greatest Guitarists of All Time" list. Laurence Juber (born 12 November 1952) is an English-born musician.  Often considered most famous for playing lead guitar in Wings from 1978 to 1980, he has since had a distinguished career as a solo fingerstyle guitarist and studio musician.  He is married to Hope Juber and they have two daughters, Nico Juber and songwriter Ilsey Juber. Samantha 7 was an American rock band founded in 1998 by C.C. DeVille, lead guitarist from the rock band Poison.  They released the self-titled album "Samantha 7" in 2000 and C.C. Deville performed lead vocals and guitar on the album.  The band also included bassist Krys Baratto (who has worked as session musician with many artists and bands, from Thomas Dolby to Guns N' Roses), ex-Cynical Side drummer Francis Ruiz and for live dates Great White's guitarists Ty Longley and Michael Lardie.  Derrick Pontier also played drums in 2001 after drummer Francis Ruiz was run over by a car in Florida. Donald James Ross, or Don Ross, (born November 19, 1960) is a Canadian fingerstyle guitarist.  He is the only person to win the National Fingerstyle Guitar Championship twice (1988 and 1996).  His album "Huron Street" reached the top ten on the "Billboard" New-age chart. Eric Tingstad (born December 16, 1954) is an American record producer, musician, songwriter and composer.  He was born and raised in Seattle, Washington.  Best known as a fingerstyle guitarist, Tingstad has performed, recorded, and produced alternative country, blues, americana, rock, smooth jazz, ambient, and New-age music.  Tingstad frequently collaborates with woodwinds player Nancy Rumbel as Tingstad and Rumbel.  He is also a principal founder, producer, electric guitarist and co-writer with the Halyards, a Seattle-based American roots rock band that includes Carl Funk and Larry Mason. Elmer Ellsworth McMeen, III (known as El McMeen) (born June 3, 1947 in Lewistown, Pennsylvania), is an acoustic steel-string fingerstyle guitarist.  His specialty is fingerstyle arrangements of sung or strongly melodic pieces, ranging from the Irish genre, to hymns, gospel tunes and pop music.  He has also composed instrumentals for guitar, and has published a book of Irish and Scottish instrumental music that he arranged for classical string trio (violin, viola and cello).  That book is called Celtic Treasures for String Trio (Piney Ridge, 2005).  He plays and arranges guitar music almost exclusively in the CGDGAD tuning.  (That tuning, developed by English guitarist Dave Evans in the 1960s, is similar to a Hawaiian slack-key tuning [CGCGAD] called "C Ni'ihau" tuning.)  "Acoustic Guitar" magazine (Oct. 2001, No. 106) called McMeen "the king of CGDGAD tuning". Billie Rex Kelley (August 23, 1926 – October 2, 2015) was an American football tight end in the National Football League who played for the Green Bay Packers.  Kelley played collegiate ball for Texas Technological College (now Texas Tech University) before being drafted by the Green Bay Packers in the 23rd round of the 1949 NFL Draft.  He played professionally for one season, in 1949.  Kelley died in Arlington, Texas in 2015.
