Roberto Zanetti (born 28 November 1956) is an Italian singer and music producer from Massa, Tuscany. As a singer, he is known under the stage name Savage and as a music producer he uses the alias Robyx.

In 1989, he recorded "I Just Died in Your Arms" (a hi-NRG remake of the Cutting Crew song), as well as a greatest hits album. In 1994, he released another album, Strangelove, containing a number of remixes of his older songs and four mixes of the song "Strangelove" (by Depeche Mode). The last single which was released by Savage was "Don't You Want Me", which appeared on his own label, Dance World Attack Records (DWA) in 1994. This track does not appear on the Strangelove album.

He worked with multiple European labels to release the album, including Polish MagicRecords and Russian RDS Records, as he was living in Poland at that time. The album was released at the beginning of 2020 and includes 14 new songs.
