Biography still a problem, could you check this?

Hi, I have translated only a couple of biographies from Czech into English so far so I still struggle with certain kind of sentences.

I can't ask you to rewrite everything or tell me about all subtle details so I only ask if whoever comes across this and notices a big mistake, please let me know. Thank you. BTW the guy is my little brother... not so little any more...

Martin Valek

Another protagonist of the evening Martin Valek, who was born in 1970, showed his talent connected with his musical family background as early as at the age of 11 by performing Vivaldi's Concerto in A minor with the Prague Chamber Soloists. A year later he presented himself (introduced his skills) in the Netherlands with the Leeuwarden Students' Orchestra.

Martin Valek studied violin at the Prague Conservatory and the Academy of Performing Arts, where he was a student with professor Petr Messiereur. Then he continued his studies in the U.S. at Yale Univerity under professor S. Harth, where he also performed as a concert master of the Yale Symphony Orchestra. In 1987, based on his exceptional talent, he was invited to play at Eastern Music Festival in Greensboro, North Carolina, the U. S. A. Soon after, he studied solo and chamber violin at the Guilford College, which hosts the above mentioned festival, with French violin virtuoso G. Poulet.

He began his solo career with performances at the Smetana Hall in Prague and concert halls of Leipzig and Dresden. Soon he started to collaborate with the Czech Television (Paganini's Variations on the G string) and the Czech Radio (Mozart's Sonatas, Beethoven's Romances, Dvorak's Romances and Massenet's Meditation). He performed Kalach's violin concerto with the Prague Radio Symphony at Music Biennale in Zagreb, Crotia and he played Sibelius' violin concerto with the same orchestra at the Intenational Music Festival of Radio Symphony Orchestras in Cologne, Germany.

Martin Valek's performances with Moravian Philharmonic Orchestra, Izmir Symphony Orchestra, Taipei Symphony Orchestra and Toronto Philharmonia proved his talent and artistic growth. In 2000 he made his first CD album on which he recorded violin concertos by Sibelius and Prokofiev with the Prague Symphony Orchestra under his father Vladimir Valek's batton.

In 1999 Martin Valek founded Epoque Quartet. It was not merely similar opinions of music that brought the four professionally experienced and outstanding solo and chamber musicians together, but above all it was their great enthusiasm for "non -classical" music genres such as jazz, rock and funk. Martin Valek has recorded three CD albums with Epoque Quartet and toured several contries with the group, among others France, Germany and Izrael.
