Rui Almeida (born 1974, Portugal) is a sound artist currently living in Guimarães. With Massa Última as his main project, Rui explores the potentialities of non-musical/natural sound sources in connection with sounds of conventional instruments. With the focus goes to pure sound collection or to the creation of environments of interaction, with non-musical sources, in an improvisational basis.

Rui's music has been released in Green Field Recordings, Impulsive Habitat, with tracks on compilations by Digital Biotope and Enough Records.
