Kurdt Vanderhoof (born June 28, 1961) is an American guitarist, best known as the lead guitarist and founding member of the American heavy metal band Metal Church.
 As early as 1976, in Aberdeen, Vanderhoof was ardently networking with local musicians and had formed a band called Tyr, which included Kirk Arrington on drums and Vanderhoof on rhythm guitar.
 In 1978 Vanderhoof joined Seattle hardcore punk band The Lewd adopting the stage name "Blobbo" on bass guitar, switching instruments to guitar the following year.
 The Lewd relocated from Seattle to San Francisco in 1980.
 Following Vanderhoof's departure from The Lewd he formed Metal Church, named after a nickname given to his San Francisco apartment.
 Vanderhoof moved back to his hometown, Aberdeen, Washington, with a vinyl single of Trash Can Baby as proof of his interlude with the Lewd.
 In the summer of 1982, he formed a heavy metal cover band named Shrapnel.
 It consisted of Tom Weber on drums, Duke Erickson on bass (both from Hoquiam), Mike Murphey ("muff", from Montesano) and a guitar player Vanderhoof had jammed with in high school(Aberdeen).
 Shrapnel played four events to warm up, including a frat party at Pacific Lutheran University, after which the other guitar player quit, having had a religious experience, unwilling to cover The Number of The Beast by Iron Maiden.
 His part was replaced by Craig Wells of Aberdeen, and Tom was eventually replaced by Kirk Arrington (also from Hoquiam) on drums.
 When Mike Murphy left the band, they recruited David Wayne for vocal duties.
 By 1983, Shrapnel had renamed itself to Vanderhoof's original band name, Metal Church.
The acoustic bass guitar (sometimes shortened to acoustic bass or initialized ABG) is a bass instrument with a hollow wooden body similar to, though usually larger than a steel-string acoustic guitar.
 Like the traditional electric bass guitar and the double bass, the acoustic bass guitar commonly has four strings, which are normally tuned E-A-D-G, an octave below the lowest four strings of the 6-string guitar, which is the same tuning pitch as an electric bass guitar.
Larry Graham Jr. (born August 14, 1946) is an American bass guitar player, both with the psychedelic soul/funk band Sly and the Family Stone, and as the founder and frontman of Graham Central Station.

"Sing a Simple Song" is a 1968 song by the soul/rock/funk band Sly and the Family Stone, the b-side to their #1 hit "Everyday People".
 The song's lyrics, sung in turn by Sly Stone, Freddie Stone, Rose Stone, and Larry Graham, with spoken word (or, rather, shouted word) sections by Cynthia Robinson, offer a simple solution for dealing with the problems and paradoxes of existence : "Sing a simple song!"
 As with nearly all of Sly and the Family Stone's songs, Sylvester "Sly Stone" Stewart was credited as the sole songwriter.
"It's Late" is a song written by Queen guitarist Brian May and performed by the band for their 1977 album "News of the World".
 The song was May's idea of treating a song as a three-act theatrical play, and the verses are called "acts" in the lyrics sheet.
 It makes use of the tapping technique a few months before Eddie Van Halen's use of the tapping technique on the "Van Halen" album.
 May told "Guitar Player Magazine" that his use of the tapping technique was inspired by Texas guitarist Rocky Athas, after seeing one of his performances at Mother Blues, a Dallas club.
 Tapping had also been previously used by other players, notably Steve Hackett of Genesis.
 The song is notable for its length and heavy, wide vocal range (E3-E6), bluesy guitar riff, and using the previously mentioned technique.
