In 1989, João Bosco, one of the true values of modern Brazilian popular music, commemorated 100 live performances with this release, and the title (the same as the recorded show) makes reference to that. After some failed attempts to be "contemporary" with plenty of electronics and reheated formulas in some of his previous albums, in this significant moment he preferred to go back to his early voz e violão (voice/guitar) days, performing with his sinuous, slimy voice accompanied only by his nervous, crackling violão. It's rewarding to see that he offers the show as a tribute to Dorival Caymmi, Silas de Oliveira, João Gilberto and Ary Barroso, whose "Aquarela Do Brasil he delivers excitingly. The rest of the album is mostly dedicated to his extremely creative and successful partnership with Aldir Blanc, visiting the duo's all times successes (many of them made famous by singer Elis Regina) with convincing and contagious energy.
