The numerous sonatas of the violinist-composer Antonio Bertali constitute a fascinating testimony as to the imperial splendour and culture at the Viennese court c. 1650. After being a violinist in the Accademia Filarmonica di Verona from 1620 to 1624, Bertali left for Vienna where one of the heights of his career was is appointment as Kapellmeister on October 1st 1649, and he would hold this position up to his death in 1669. Even though famous as a violinist in his lifetime, Antonio Bertali is not one of the bestknown composers for violin.

Several masses with large orchestration attest to the outstanding compositional skills of the Salzburg master Heinrich Ignaz Franz Biber (1644-1704) in coping with large ensembles. As usual in Salzburg, Biber expects polychoral performances. The church music at the Salzburg cathedral drew its orientation from the performance practice in Venice. The Missa Alleluia was probably composed after 1690 and certainly before 1698, because a manuscript was made in Kremsmunster that year. The original score and sheets from Salzburg are lost. Excellent copies have been preserved at the Upper Austrian abbey at Kremsmunster: they serve as a basis for the present recording. Biber has fully exploited the possibilities of Baroque Instrumentation in the Missa Alleluia: a chorus with 2 sopranos, 2 altos, 2 tenors and 2 bass voices grants him a large number of combinations of voices and thus constant change of timbre. The strings choir also has six parts, with both violins often conducted virtuosically. A chorus with 3 trumpets and 2 cornetti is even surpassed in tonal mass by the chorus composed of 2 clarini, 4 trumpets, and timpani. This large number of trumpets emphasizes the cheerful character of the work and is very luxurious by Austrian standards.

Franz Josef Aumann (1728-1797) was a free and innovative composer. His chamber music is really worth exploring as they provide a lively and interesting listening experience.

Gunar Letzbor and his ensemble Ars Antiqua Austria are proven specialists for Austrian baroque music. During recent years, they have rediscovered, performed and recorded polychoral Festive Masses by Weichlein, Ramhaufsky and Hochreither and thus Georg Muffat's magnificent 'Missa in labore requies' is a logical choice of repertoire. This work is the only surviving church music by Georg Muffat and is overwhelming in sonic impact and profundity but also a richness of melodic invention. In its polychoral design, the work is in the tradition of Salzburg Festive Masses, reflecting in their extraordinary musical opulence, the almost boundless material wealth of the prince bishops who commissioned them.

The Habsburg Imperial Court was a melting pot of many different cultures in which the zest for living of southerners, the Slav melancholy, French formalism, Spanish courtliness and the original German-speaking Alpine cultural region intermingled. Together with his Ars Antiqua Austria ensemble, Gunar Letzbor occupied himself over a ten year period to produce this 10CD "Klang der Kulturen" box, a musical tour of the individual countries that formed the roots of and influences on the music of baroque Vienna, documenting them in live recordings, with each CD representing one country.

Gregor Werner (1695-1766) began directing the fortunes of the Esterházy court band, the Hofkapelle, on 10 May 1728. He was an industrious man. Forty Masses, three Requiems, three Te Deums, four Offertories, twelve Vespers, twelve Good Friday oratorios, approximately eighteen oratorios, a hundred and thirty-three antiphons and a multitude of instrumental pieces and minor works testify to his fertile creative spirit.

Franz Joseph Aumann was born in 1728, in the city of Traismauer and studied in Vienna. In 1753 aged only 25 he established himself at St. Florian, where he remained until his death in 1797. He composed 12 Requiems, in addition to masses, motets, litanies, offertories and oratorios. In the Requiem recorded here the listener is confronted with early Baroque opulence: the use of almost exclusively solo instrumental parts and singers bring a transparency and layered effect to the composition.

Wenzel Ludwig Edler von Radolt’s collection of lute music entitled ”To my most true and confiding friend”, inclined both to the merry and to the sad humours, herewith in the company of other faithful vassals of our innermost sensibility’ was printed in 1701 in Vienna by J(oh)ann Michael Nestler and bears a dedication to the then‚ Roman King’ Josef I.
Radolt was of Austro-Italian aristocratic descent. He was born and died in Vienna. According to his own account, he spent his life ”so allured by the beguiling countenance of most pleasurable music, as to dedicate the course of my life to her“. The ‘Most true and confiding friend’ is the only work of Radolt that survives today.

A ubiquitous Viennese figure in the early 1700s, Francesco Conti was one of several gifted Italian Baroque composers who settled in foreign lands. If Caldara remains the most durable Italian figure in Vienna, Conti's star — on this evidence — deserves to be dusted down and given a second chance. These four cantatas from eight Cantate am istromenti probably date from the first decade of the century and feature the most delectable plethora of obbligato instruments imaginable.

The historical-instrument ensemble Ars Antiqua Austria under violinist/conductor Gunar Letzbor has specialized in neglected repertory of the eighteenth century, and few composers fit their aims better than Antonio Caldara, a Venetian trained in the grand tradition at St. Mark's cathedral. He had a distinguished career that took him to Mantua, (perhaps) to the then-Austrian court at Barcelona, to Rome, and finally to Vienna itself, where he became vice-kapellmeister under emperor Charles VI. As with other composers in this milieu, most of his production was vocal.

Antonio Maria Bononcini (1677 - 1726) is the younger and lesser-known brother of Giovanni Bononcini (1670 - 1747). He was one of a number of Italian composers who were active at the imperial court in Vienna, and introduced the newest trends in Italian music to the Austrian capital. His brother also did belong to this group of composers, as well as Ziani and Ariosti. The chamber cantata was one of the genres these composers paid attention to as listening to cantatas was part of the entertainment at the court.

Eduard Melkus brought Heinrich Ignaz Franz Biber's (1644-1704) Rosary Sonatas (Rosenkranzsonaten) to new life with his groundbreaking 1967 recording; in the six decades that have passed since then, the pieces, which are as virtuoso as they are meditative in mood, have conquered a firm place in the discographies of ambitious baroque violinists. The Austrian violinist Gunar Letzbor has been considered one of the leading interpreters of this famous cycle since he recorded his interpretation on album for the Arcana label in 1996. The success was overwhelming: the critics were enthusiastic and the recording is still today available in the label's catalogue.

Ars Antiqua Austria was founded in Linz in 1989 with the aim of introducing audiences to the roots of specifically Austrian baroque music played on period-instruments. The music performed at the imperial court in Vienna at this period shows the strong influence of Italy and later of French forms, while Spanish court ceremonials also shape the character of the works. The typical Austrian sound of the period also betrays the influence of the many Crownlands. The political and social boundaries of Austria in the baroque era were far wider than in the 20th century.

Romanus Weichlein was an Austrian composer and organist of the mid Baroque period who published a set of 12 sonatas for strings and continuo in 1695 entitled Encaenia Musices.In some of the sonatas the strings are joined by 2 trumpets to spectacular effect and it's very clear that these admirable compositions were influenced by Heinrich Biber's Sonatae Tam Aulis Servientes of 1676.Weichlein is believed to have met Biber when in Salzburg and it's quite apparent that Biber was to have a big influence on the slightly younger composer.
