The most successful Hungarian rock band in history, Omega is one of the rare bands to have been known outside in his country. Their music is a combination of Eastern European prog with a bit of symphonic and a bit of psych prog. The result is a dark orchestrated sound combined with extended improvisation. Their discography actually starts in the early 60's, and goes in till today in a more modern register.
The 18th set of Bach's cantatas contains exclusively works of the third yearly cycle from Leipzig. Unlike the first two Leipzig yearly cycles, this one extends over a longer period: from June 1725 until 1727. The works in this set belong essentially to the years 1725-26 and are in some cases chronologically contiguous (BWV 187 and 45; BWV 98, 55, 52), with the result that the original sequence can be easily grasped.
The cantatas of volume 20 combine the concluding items from the "Picander" year of 1728-29 with a series of cantatas from the first half of the 1730s. A special feature is the inclusion of a hitherto completely unknown sacred work from Bach’s Weimar period, discovered as recently as May 2005 by Michael Maul (who works in the Bach-Archiv in Leipzig) in the Herzogin Anna Amalia Library, Weimar. This aria of praise dating from 1713, preserved in a newly discovered original source and now assigned the BWV number 1127, supplements Bach’s Weimar cantatas in a felicitous manner. Above all it is the first new work to add to Bach’s vocal output for 70 years, since the discovery of the cantata fragment “Bekennen will ich seinen Namen”, BWV 200.
The cantatas of volume 19 can be relegated to three groups: Four works (BWV 72, 88, 129 and 193) belong to the third Leipzig series, lasting from 1725 to 1727; five (BWV 145, 159, 171, 174 and 188) belong to the group known as the Picander cycle of 1728-29, which was not completed or has not survived complete; two works (BWV 51 and 117) belong to the period after 1730, in which Bach composed new church cantatas only sporadically.
