Clarence "Gatemouth" Brown (April 18, 1924 – September 10, 2005) was an American musician from Louisiana and Texas known for his work as a blues musician, as well as other styles of music.

He was an acclaimed multi-instrumentalist, who played an array of musical instruments, including the guitar, fiddle, mandolin, viola, harmonica and drums. He won a Grammy Award for Best Traditional Blues Album in 1983 for his album, Alright Again!. He is regarded as one of the most influential exponents of blues fiddle and has had enormous influence in American fiddle circles. Brown's two biggest musical influences were Louis Jordan and T-Bone Walker.

Brown was born in Vinton, Louisiana, and raised in Orange, Texas. His professional music career began in 1945, playing drums in San Antonio, Texas. He was given the nickname "Gatemouth" by a high school teacher who said he had a "voice like a gate”. His career was boosted when he attended a concert by T-Bone Walker in Don Robey's Bronze Peacock Houston nightclub in 1947;Walker became ill, and Brown took up his guitar and quickly wrote and played "Gatemouth Boogie", to the delight of the audience.
In 1949 Robey founded Peacock Records in order to showcase Brown's virtuoso guitar work. Brown's "Mary Is Fine" backed with "My Time Is Expensive" was a hit for Peacock in 1949. A string of Peacock releases in the 1950s were less successful commercially, but were nonetheless pioneering musically.
Particularly notable was the 1954 instrumental "Okie Dokie Stomp", in which Brown solos continuously over a punchy horn section (other instrumentals from this period include "Boogie Uproar" and "Gate Walks to Board"). "Okie Dokie Stomp" was also recorded by Cornell Dupree in the 1970s, who also had a
commercial success with it. As for his gutsy violin playing, Robey allowed Brown to record "Just Before Dawn", his final release on the Peacock label, in 1959.

In the 1960s Brown moved to Nashville, Tennessee to participate in a syndicated R&B television show, and while he was there recorded several country singles. He struck up a friendship with Roy Clark and made several appearances on the television show Hee Haw. In 1966, Brown was the musical director for the house band on the short-lived television program, The !!!! Beat.
When Gate began to rebuild his career in the '70s, he was determined to do things his way. Country, jazz, even calypso now played a prominent role in his concerts; he became as likely to launch into an old-time fiddle hoedown as a swinging guitar blues. He turned up on Hee Haw with pickin' and grinnin' pal Roy Clark after they cut a sizzling 1979 duet album for MCA, Makin' Music. In 1979, through his manager at the time, Jim Halsey, Brown embarked on a 6-week, 44 concert tour of the Soviet Union.

In 1999, Brown was inducted into the Blues Hall of Fame. In his last years, he maintained a full touring schedule, including Australia, New Zealand, South America, Africa and Eastern Europe. His final record "Timeless" was released in 2004. Acclaimed discs for Rounder, Alligator, Verve, and Blue Thumb in the '80s, '90s, and 2000s have proven that Gatemouth Brown is a steadfastly unclassifiable American original.

His home in Slidell, Louisiana, was destroyed by Hurricane Katrina in August 2005, although he had been evacuated to his childhood hometown of Orange, Texas before the storm hit. He died there on September 10, 2005, at the apartment of a grandniece, at the age of 81. Brown is buried in the Hollywood Cemetery in Orange. (Edited from Wikipedia & AllMusic)
