Opa was a mixture fusion band led by the Fattoruso brothers and Ruben Rada that broke up after two records in 1976 and 1977. This is a recording of their reunion live performance in 1987, about 10 years later. It is full of the realistic atmosphere of that time. The B-side is especially amazing. This is a cassette version with a different jacket released from Melopea in Argentina. The sound quality of the cassette and the feeling of the live recording is something you should definitely enjoy.
