Jan Akkerman, born in 1946, can be considered to be something of a child prodigy in that having played accordion from the age of three, he began guitar lessons at the age of five, formed his first band aged 12 and cut his first record at the age of 14 or 15.
On Tabernakel, Akkerman is accompanied by at least four other such childhood prodigies. These are
Arnold Eidus (1922-2013) violinist. Eidus made his performance debut at Carnegie Hall aged 11.
Harry Cykman (1921-1994) violinist. Cykman made his debut as a violinist in 1930 at the age of nine (for promotional purposes, a year was shaved from his birth date).
Emanuel Vardi (1915-2011) violinist, violist and composer began to play at the age of three. He is one of only two violists in the world to have ever given a solo recital in Carnegie Hall.
George Ricci (d 2010) cellist. One of the great American cellists, his brother was the great violinist Ruggiero Ricci. His sister Emma was also a violinist with the Metropolitan Opera. Born in California and raised by Italian immigrants, George and Ruggiero performed together as children.
