Arlen Roth: Arlen Roth (born October 30, 1952 in New York, U.S.) is an American guitarist, recording artist, performer, tutor, and author.  His first solo album won the Montreux Critics' Award for Best Instrumental Album of the Year in 1978.  He was a regular columnist for Guitar Player magazine from 1982 to 1992.  He has performed and recorded with artists such as Bob Dylan, Danny Gatton, John Entwistle, John Prine, Kate Taylor, James Taylor, Livingston Taylor,  John Sebastian, Rick Wakeman, Paul Simon (as well as Simon and Garfunkel), Ry Cooder, David Lindley, Sonny Landreth, Levon Helm, Bill Kirchen, Duane Eddy, Steve Morse, Albert Lee, and Phoebe Snow.  Roth is a Telecaster enthusiast, and has written the book "Masters of the Telecaster", which details the techniques and licks of many famous Telecaster guitar players.  As a solo artist Roth performs frequently with his younger daughter, Lexie Roth, a recording artist, performer, and songwriter in her own right.  He was greatly influenced by Clarence White of The Byrds' string bending style, but at the age of 14, he did not know White had invented a "B-string bender" for his Telecaster, so Roth developed a new style of doing this with fingers alone.  He thus innovated many string-bending styles on the guitar, simulating a "pedal steel" guitar.  He is also an innovator in the use of "harmonics" within guitar playing.
