"Estratosférica ao Vivo" is not just the record of a Gal Costa show. It is the portrait of the artist reaching the 70 years of life, 50 of them dedicated to music. The show "Estratosférica" crowns the new artistic phase of Gal, more and more interested in connecting several tips of the history of the music of Brazil, joining the composers of its generation to names of the new national scene. The script, created by Marcus Black, was very good at this idea. Sewing songs by Caetano Veloso, Tom Zé, Luiz Melodia, Jards Macalé and Waly Salomão, Carlos Pinto and Torquato Neto, Roberto and Erasmo Carlos - a series of tropicalist and post-tropicalist works that until now serve as reference and feed the new generations of music.
