Legg is world-renowned, hailed by the St. Petersburg Times as "a guitarist of great power, invention and versatility."
He, however, doesn't consider himself as eclectic as he's made out to be.
"I play American guitar," he said. "I wanted to imitate the pedal changes. What I play is more of a reaction to what American guitar has become."
As a boy, American music was prohibited in England, but when he was an early teenager he would listen to 1950's pop music from Radio Luxemborg. Though trained in classical music -- which "informs my melodies and harmonies" -- he taught himself to play American guitar, without any teaching materials.
He learned first on the electric guitar, and began to play gigs throughout England and Ireland. One day, someone asked him to play the acoustic guitar for their party.
"I saw something in it," Legg said.
He's since found a way to blend the styles of the electric and the acoustic guitars. He finger-picks, which allows him to create harmonies using different strings simultaneously.
"It's good therapy," he said.
Mark and Karen Carey heard of Legg while on a trip through Los Angeles. They were headed to McCabe's Guitar Shop, a store as widely known for its concerts as it is for its guitars. Legg was playing at McCabe's that night, and though they didn't make the concert, they heard of Legg, and decided to bring him to Spencer several years later.
On Friday night, before returning to London with his wife, Legg sat in the Careys' backyard and gave a house concert. Of all of the venues he plays at, Legg admits that he really likes playing house concerts.
"It's like we're taking back the music," he said.
