I ran across Shahin & Sepehr in the 90's when an Iranian friend introduced me to their music.
They came to the U.S. on a peace mission. They are Persians.
They felt our countries were better off exchanging the good things of life rather than the bad things of death.
So they speak the language of music which is more often than not the music of peace.
Like the Doobie Brothers said, Listen To The Music, not the drums of war.
