Dermeval Miranda Maciel, best-known as Roberto Ribeiro. (Campos dos Goytacazes, July 20, 1940 – January 8, 1996) was a Brazilian samba singer.

The name Astor Piazzolla may be forever linked with the tango, but the master composer/artist had another passion that is finally revealed on this release: chamber music. Written primarily in the 1940's, before Piazzolla developed New Tango, these pieces demonstrate his flair for serious classical composition. The influences of Alberto Ginastera (his Argentine teacher), Bartok and Hindemith clearly steered the impressionable Piazzolla in a different direction. In addition, several tango-flavored chamber pieces composed in the 1960s and 1970s complement this unique collection. Most of the works on here have never before been recorded. The album features noted pianist Allison Brewster Franzetti, violinist Hector Falcon, violist Nardo Poy and cellist Eugene Moye.
