Larry Keel and Adam Aijala are two great guitarists who play in various bands and styles. I have dicscovered them as a duo from a podcast which is no more available. Larry Keel and Adam Aijala have played as a duo in 2009 and 2010.
You can find a recording of a concert of Larry Keel and Adam Aijala in good quality on the archive.org website:
From his bio on the official hompage:
Over the years Larry Keel has become a world-class flatpicking guitarist, and that talent has earned him legendary status with fans and the highest respect amongst his musical peers. In recent performances Larry has led bands involving such industry icons as Tony Rice, Jack Lawrence, Mike Marshall, Darol Anger, Curtis Burch (New Grass Revival), Vassar Clements, Joe Craven, Jim Lauderdale, Eddie Adcock;
Adam Aijala plays guitar in the Yonder Mountain String Band (YMSB). On their homepage I found the following:
As a young teen, Adam loved skateboarding and listening to punk and hardcore music.
He learned power chords first, playing dozens of short punk tunes. In his early years of high school, he added metal bands like Metallica and Slayer to his repertoire. Shortly after, Adam’s musical tastes began to shift. He began listening to Led Zeppelin, Jimi Hendrix, and even the Grateful Dead. Desiring a new sound, Adam picked up his first acoustic guitar at age 17.
I have compiled a playlist with Larry Keel and Adam Aijala, but the audio quality is not so good on most of the videos.
