Som Imaginário was a famous Brazilian group responsible for support the singer Milton Nascimento. The group released 3 albums between 1970 and 1973.
The band in its original lineup had Wagner Tiso (piano and keyboards), Tavito (vocals and acoustic guitars), Zé Rodrix (vocals, keyboards and flutes), Luiz Alves (bass), Robertinho Silva (drums) and Frederiko (guitars) and their 2 first records are more folk/psychedelic.

In 1973 the band was a quartet with: Wagner Tiso (piano and keyboards), Frederiko (guitars), Luiz Carlos (bass) and Robertinho (drums). With Wagner Tiso as a leader they were now almost instrumental and this is by far their best record.

Zé Rodrix were already with his trio Sá, Rodrix & Guarabira and Tavito still participate in the album as a guest playing acoustic 12 strings guitar in 3 tracks. But it's the hands of the maestro Wagner Tiso that makes all the difference in the world in Matança Do Porco (1973).

'Armina' and 'Matança Do Porco' are the keytracks, Progressive pearls lost in the haze of time. This is one of the true Brazilian classics.
