Since coming to the United States, Mr. Goryachev has continued his lifelong love affair with flamenco while deepening his involvement with the classical style. His repertoire now includes classical solos, chamber music and guitar concertos and more than six hours of flamenco solos by such composers as Paco de Lucía, Vicente Amigo, Manolo Sanlucar, Rafael Riqueni, and others.
As the flamenco repertoire is for the most part unpublished, Mr. Goryachev has performed the somewhat incredible feat of transcribing entirely by ear from the recordings.​
Grisha strives to keep alive older flamenco masterpieces that now exist only on records, by performing them in concerts. Grisha exposes the audiences to some of the best guitar compositions flamenco has to offer. Instead of merely copying, he creates his own interpretations of these masterpieces, using dynamics and tone colors usually associated with classical music.
