The first question to ask must be: how could it possibly come about that certain essential works by a composer which display no flaw or failure in musical conception or compositional execution stayed dormant in libraries for well over two hundred years and had to wait so long for publication and audience attention? Three concertos for double bass and orchestra by Johann Matthias Sperger, who was not just a composer but also the most renowned double bassist of the 18th century, performed and recorded here by orchestra and soloist according to their original scores. Sperger’s treatment of the solo double bass in a way quite new in his day as well as the execution of the orchestral part recall the Cello Concertos of no less a figure than Joseph Haydn. Already just the tonal range demanded here, spanning four and a half octaves, shatters all previous conceptions and lets the double bass enter those cantabile spheres once peculiar to the cello or violin. Melody and virtuosity leave nothing to be desired and demand of the soloist true mastery of his instrument. All three double bass concertos on this album are three-movement concertos. In all of them the first and third movements are spirited, each with its respectively striking theme, and virtuosically constructed, the outer movements in all cases employing wind instruments: 2 oboes and 2 horns, and in Concerto No. 3 also kettledrums and trumpets. The great soloist’s idea of enriching the orchestral colours of Concerto No. 4 with a dulcimer must be seen to be born out of the partly folkloric quality of this music. Sperger has the slow second movements accompanied by strings alone, so as to allow the solo double bass room to develop its melodies. These movements emanate a sense of placid contemplation, forming a counterpoint to the forward-pressing vigour of the outer movements. The soloist uses gut strings, as was common practice at the time of the works’ composition well over two hundred years ago, bringing out the warm sound of the instruments. Used in this recording were: for Concerto No. 2 an Anton Posch double bass (1736, Vienna); for Concerto No. 3 one by Johann Jacobus Ertl (1789, Pressburg) and for Concerto No. 4 one of an unnamed manufacturer (ca. 1810, Vienna). The chamber orchestra Collegium Wartberg 430, led by the soloist Ján Krigovský, provides highly authentic accompaniment. To do justice to history and for the pleasure of today’s audience the present recordings were made in the same auditorium as Johann Matthias Sperger first presented these concertos in: the “Hall of Mirrors” in the Primate’s Palace of Bratislava (formerly Pressburg).
