The next piece is easily recognizable: the Sextet KV 493b/3 in B flat major is nothing more than a work recorded in the Philips Complete Mozart Edition. It’s the third of five Divertimentos, all in the same key (App. C 17.01-05), which are probably spurious according to critics. However, amateurs love them (the Divertimentos, not the critics :D) and play their arrangement for piano by an anonymous author: in that version, they’ve been made into the so-called ‘6 Viennese Sonatinas’:
Apparently, these Sonatinas are played not only by amateurs:
As the first one, the last work recorded on this CD is disconcerting: an unidentified Serenade KV deest in E flat major, i.e. an Octet with double bass ad libitum that doesn’t sound Mozartean nor reminds of the ‘official’ Mozart Serenades for winds (KV 361, 375 and 388). Have you seen it in the Köchel catalogue? Neither have I. This composition is just your average decent Divertimento.
It’s hard to find its author, but according to these two sites it should be “possibly by Vinzenz Masek (1755-1831)” (it is not known on which basis this attribution was assumed), namely Václav Vincenc Mašek, a Czech composer who wrote operas, symphonies, piano sonatas and concertos, chamber music, masses, cantatas, lieder and pieces for glass harmonica.
