Franz Xaver Wolfgang Mozart was born in Vienna, four months and ten days before his father's death.
"In April 1805, the thirteen-year-old Wolfgang Mozart made his debut in Vienna in a concert in the Theater an der Wien.
Needing money, in 1808, he traveled to Lemberg (now Lviv), where he gave music lessons to the daughters of the Polish count Wiktor Baworowski.
In the 1820s, Mozart was one of 50 composers to write a variation on a theme of Anton Diabelli for part II of the Vaterländischer Künstlerverein.
Mozart died from stomach cancer on 29 July 1844, in the town of Karlsbad (now Karlovy Vary) where he was buried.
Franz Xaver Wolfgang had a relatively small output (his opus numbers only go up to 30) and after 1820 he seems to have given up composing almost entirely; in particular, there is an 11-year gap (1828 to 1839) when he seems to have not written anything.
The first concerto could pass for one of his father's late (K. 550 and above) works, except for a youthful exuberance and the piano's tessitura which had been expanded in 1795, just after Mozart senior died.
The second concerto is more contemporary to the 1810s with a more virtuosic piano part showing hints that the younger Mozart was developing his own style.
