Robert Wetzel born of Dutch, Indonesian, and Chinese lineage, began serious study of the classical guitar at age fifteen with Darryl Saffer at Southern Methodist University. While still in his teens, he was a performer in the guitar master classes of Christopher Parkening, Oscar Ghiglia, the guitar duo of Ako Ito and Henri Dorigny, Robert Guthrie, and Pepe Romero.

In 1972, he began private studies with Angel Romero that continued for several years. In 1975, Wetzel was awarded a full scholarship by Pepe Romero to participate as a performer in a master class conducted annually by Mr. Romero for five consecutive years in Houston, Texas as well as two master classes by Joaquín Rodrigo and Federico Moreno-Torroba. Private guitar studies coincided during this period and a few years thereafter with Pepe Romero and Celedonio Romero. Undergraduate studies with Robert Guthrie at Southern Methodist University earned him a BA Degree in musical performance and he was the first guitarist to earn a Master of Music Degree from San Diego State University under the guidance of Celin Romero.

Aside from the Odeum Guitar Duo, Wetzel is a frequent performer in solo, chamber music, and orchestral concerts and currently he resides in San Diego where he is on the music faculty at the University of San Diego, University of California San Diego, Grossmont College and San Diego State University.

Fred Benedetti was born in Sasebo, Japan and began playing the guitar at age 9. In 1986 he was one of 12 guitarists chosen worldwide to perform in the Master Class of Andrés Segovia at USC where Guitarra Magazine wrote, "...Fred Benedetti amazed the audience with his performance of the (Bach) Chaconne..." He has also been a performer for the master classes of Pepe Romero, Christopher Parkening, Federico Moreno-Torroba, George Sakellariou, and David Grimes. Fred has performed in the United States, England, Germany, the Czech Republic, Canada, Taiwan and Mexico and locally with the San Diego Symphony, the San Diego Opera, the Starlight Opera, the American Ballet Company, the Old Globe Theatre, Luciano Pavarotti, and jazz artist Dave Brubeck.
