A soloist with the Lithuanian National Philharmonic, Danielius Sadauskas was born on 15 June 1940 in the village of Petroškos (Lazdijai dist.). Died in 2015. He received his musical education at the Vilnius Juozas Tallat-Kelpša Higher School of Music (at present Vilnius Juozas Tallat-Kelpša Conservatoire) and the Lithuanian State Conservatoire (at present Lithuanian Academy of Music and Theatre), where he studied under Professor Zenonas Paulauskas and from which he graduated as an opera soloist and chamber singer in 1967.
Until 2001, Sadausakas worked as a soloist with the Lithuanian National Philharmonic and taught at the Lithuanian Academy of Music and Theatre.

His repertoire includes about 1,500 works of various epochs and styles. He has given over 5,000 concerts, has appeared in many TV productions and musical broadcasts, and has recorded 7 LPs and 10 CDs. He has recorded about 20 hours of music for Lithuanian Radio, and his recordings have also been used by other composers and performers and publishing institutions, such as the “Vilniaus Bažnyčios” CD-ROM, the Institute of Mathematics and Informatics under the auspices of UNESCO, Martynas Mažvydas’ The Year of Lithuanian Book, The Life and Work of Vincas Kudirka.

Sadausakas was the first to study, restore and make radio and CD recordings of ancient Lithuanian songs: seven out of 18 Martynas Mažvydas’ songs were released on CD-ROM and distributed in foreign countries by UNESCO. He also restored chanted poetry of early Lithuanian classics, such as Antanas Strazdas’ idylls, Antanas Baranauskas’ canticles, Pranas Vaičaitis’ elegies, songs collected by Jonas Basanavičius and Vincas Kudirka, elegies by Antanas Vienažindis and Pranas Vaičaitis, and Vydūnas’ musical Rambynas.
The poet Marcelijus Martinaitis writes in the sleeve notes to the CD of poetry by Maironis: “I have several times heard Danielius Sadauskas chanting poetry by our classics, such as Mažvydas, Strazdas, Baranauskas, Vienažindis and Kudirka. And now it is also Maironis, whose poetry heralded the rebirth of Lithuania’s independency. His chanting has made an extraordinary impression on me, and not only because these poetical works have been performed by a real master of solo singing. When listening to him, it seems that you hear a voice coming from the origins of our writing, from catechisms and ancient hymnals, from the times of the ban on the Lithuanian press. […] That is why I cannot say that Sadauskas simply sings our ancient poetry: he chants it like the most sacred legacy of our nation.”

The musicologist Jonas Bruveris writes in the sleeve notes to the CD of Maironis’ songs: “It was in archives that these songs, which had been written down from folk singers, were found. Algimantas Bražinskas, Vytautas Mikalauskas, Valentinas Bagdonas and Mindaugas Urbaitis wrote the songs at Sadauskas’ request: the idea was to keep the tradition of song-writing. The improvised accompaniments of the saxophone and kanklės in two songs as well as the arrangements of other songs for solo voice were made also at his request.”
In 2006, Sadauskas recorded a double CD of 30 songs to Maironis’ poems. The album contains well-known classical compositions by Juozas Naujalis, Česlovas Sasnauskas, Juozas Tallat Kelpša and Aleksandras Kačanauskas, a number of modern songs, and folk-influenced arrangements of chanted poetry. The CD was released under the National Programme for the Promotion of Lithuanistic Traditions and Heritage.

In 2007, the singer recorded a double CD of classical music, featuring compositions by Schubert, Schumann, Haydn, Grieg, Telemann, Beethoven, Britten, Mahler, Brahms, Barber, Franck and Bach.

Sadauskas has given concerts in Poland, Ukraine, Kaliningrad, North Caucasus, Middle Asia, Germany, Finland, Sweden, Vietnam, Australia, Switzerland and the United States. In 1998, he was invited to sing at the events to mark the centenary of the Lithuanian national anthem, which were held in the USA, and in 2007 performed at the commemoration of the 145th anniversary of the birth of Maironis in Switzerland. He is often invited to perform at national celebrations, Lithuanian classics’ anniversary events, and at such festivals as the Spring of Poetry and the Musical Autumn.

A CD entitled “Vincas Kudirka. Music, Poetry, Recollections”, featuring new compositions to texts by Kudirka, written by contemporary composers on the initiative of Sadauskas, is to come out in 2008. Also under preparation is a CD with the title “Songs of the Homeland”, dedicated to the Millennium of Lithuania and the 600th anniversary of the Battle of Grünwald.
In 1986, Danielius Sadauskas was given the honorary title of Meritorious Artist of Lithuania. For the restoration and distinctive interpretation of the ancient Lithuanian chanted poetry, he became a laureate of the Spring of Poetry in 1997.

Danielius Sadauskas is the founder of the Muzikinė Auka (Musical Offering) Charity Foundation, the Pilis (Castle) Association for the Restoration of the Grand Duke’s Palace, and the Support and Charity Foundation for the Perpetuation of the Name of Doctor Vincas Kudirka.
