I again agree with what you say here.
It was of course the state/organised church alliance which underpinned much of western European history from the start. The extent of that influence in the careers of Beethoven, Haydn and Mozart (in particular) is deliberately hidden because moves towards a 'secularised' society of the kind pushed by the 'enlightenment' could not admit to its true origins - being none other than the same vested interests as before. So that these iconic composers appear to 'float' through the society and the musical world of their own times, disembodied and rarely appreciated within their real musical and other contexts. The average music lover hears little, if any of the music of their 'lesser' contemporaries and their own influences. It's deliberate and it's relentless. So dozens, even hundreds of names are buried, deliberately edited out of the 'official' history, regardless of their own talents, often their clear association with the 'giants', with all the absurdities this creates.
Easter Island is far from where most people live. So too are the icons 'they' have created. They are very, very far, from the musical, social and other realities of those times.
Yes, I thought Stanisława Kostki would be of interest.
According to Macek, the first performances of Mozart operas at the residences of Lobkowitz took place at Raudnitz in Bohemia in the fall of 1798, thus before the theatre itself was actually completed. An ensemble of singers from Prague, organized by Franz Strobach, Kapellmeister at the Lobkowitz Loretto Church, was invited to perform Die Entführung aus dem Serail and Cosě fan tutte; the orchestra was enlarged with the addition of local amateur players.
Here is music equal to anything of Beethoven in Onslow's 4th (last) symphony -
Georg Onslow
Symphony No. 4
3rd Movement
(Andantino molto cantabile)

Regardless of what we think about composers and the true origins of music that is associated with them, I don't think anyone would disagree this music deserves to be recognised and heard alongside that of Beethoven and others.
