Alegre Corrêa, musician and composer until then based in Austria, enters this story when he was instigated by conductor Christian Muthspiel to compose reflections on the great work of Darius Millaud. Alegre accepted the challenge, which consisted of doing the reverse process: a Brazilian composer, far from his country, looking at him with the objective of identifying the original influences of the work Saudades do Brasil and, only then, composing other songs inspired by Millaud's . In two months of intense research and introjection into music, Alegre Corrêa reinvented, in a  differently, the songs: Sorocaba, Laranjeiras, Sumaré, Gávea, Corcovado and Leme. This creation was reason enough for the first concert partnership between Alegre Corrêa and conductor Christian Muthspiel. The program, with original songs by Darius and those by Alegre Corrêa, was presented at:
 
Mar/2001- Linz (AU), at Brucknerhaus, with Bruckner Orquestra;
Oct/2004 – Vienna (AU), at the Konzerthaus, with Camerata Salzszburg;
Dec/2007 – Hannover (AL), at the Hannover Opera, with the Hannover Orchestra.
 
In 2012, Alegre Corrêa was once again invited to play with his group, together with  with the Tonkünstler orchestra, from St. Pölten under the baton of conductor Christian Muthspiel, in the Plug In project. Unlike previous presentations, in which the orchestra played Millaud's works alone and the Alegre Corrêa group the reflections, Alegre proposed that everyone  to play together only the reflections and others of their songs. The concerts were then held at:
 
Feb/2013 - Festspielhaus, in St. Pölten;
Feb/2013 - Main hall of the Vienna Musikverein, one of the most renowned concert halls in the world.
May/2014 - with the Unicamp Orchestra - Campinas
 
Saudades do Brasil is, originally, a suite written by Darius Millaud, a French composer and professor, who lived in Brazil in 1917 and 1918, having acted as secretary to the French ambassador, Paul Claudel. At the time, Millaud was greatly influenced by Brazilian rhythms, assiduously attending  the salons and the musical elite of Rio and living with Heitor Villa-Lobos, Alberto Nepomuceno, Oswaldo Guerra and Luciano Gallet. Only in 1920, already back in France, he wrote Saudades do Brasil, his greatest success, a collection of 12 songs, each one dedicated to a Rio neighborhood.
