Thalberg's first American season ended with a concert on 29 July 1857 in Saratoga Springs, NY. On 15 September 1857 he gave another concert in New York, starting his second season. With very few intermissions he was busy until his last concert on 12 June 1858, in Peoria, IL. By then he had visited nearly 80 cities and given more than 320 regular concerts in the United States and 20 concerts in Canada. In addition, he gave at least twenty free concerts for many thousands of schoolchildren. Thalberg also gave a series of solo matinees in New York and Boston at which he played own works as well as chamber music. From 1857, the violinist Henri Vieuxtemps toured with Thalberg. They played works by Beethoven, and Duos composed by Thalberg.
