Mozart’s return to Vienna in 1781 initiated a remarkable period of inventiveness and productivity. In late 1784 he wrote the Piano Concerto No. 19 in F major, a work Mozart performed in Frankfurt on the occasion of Leopold II’s election as Holy Roman Emperor and which is notable for its rhythmic vivacity and sense of colour. In 1786 he wrote the Piano Concerto No. 25 in C major – a work that stretched the concerto genre considerably with its operatic qualities and dramatic dialogue. Ignaz Lachner’s ingenious transcriptions show a complete grasp of Mozart’s idiom, incorporating much instrumental detail and reinventing the music’s underlying dramatic scheme within a chamber context.

Mozart himself saw the advantages of creating more accessible versions of his concertos in reduced instrumentation. Ignaz Lachner followed common 19th-century practice by leaving the piano parts of these concertos intact and making splendid transcriptions of the orchestra parts using only a string quartet with added bass. K. 488 and K. 491 are two of Mozart’s greatest and most popular piano concertos. These chamber versions throw an intense and intimate new light on familiar music. Alon Goldstein is one of the most original and sensitive pianists of his generation, admired for his musical intelligence and dynamic personality. His career as a soloist has taken him all over the world, working with leading orchestras and conductors.

Domenico Scarlatti is best remembered for the hundreds of single-movement keyboard sonatas he composed for his pupil the Infanta Maria Bárbara, who married the heir to the Spanish throne in 1728, taking her music master with her from Lisbon to Madrid. Scarlattis panache and inventiveness is always on show in these compact sonatas, their delicacy and refinement hiding some surprising explorations of unexpected keys, and technical demands such as hand-crossing and chains of sixths and thirds that would have posed some interesting challenges to his clearly talented pupil.
