During spring and summer 2006, Pérez toured Europe with his band, along with Therion and Tristania, promoting the album Free Fall into Fear, which was published a year earlier.

However, in November 2006, Pérez finally abandoned Trail of Tears with other members (except the vocalist Ronny Thorsen) because of musical differences and monetary losses.

[2] Two other more experimental musical projects with lesser-known bands have been Stemplet Falsk ("False Stamp" in Norwegian), which he formed with a former Trail of Tears colleague, guitarist Runar Hansen and, more personally, Sonido Latino (Latin Sound).

In November 2017, Pérez left Sirenia definitively before a European tour and his position was occupied by the Austrian drummer Roland Navratil.

Jonathan Pérez left Chile in 1982 (at the age of 3) together with his family and grew up in the city of Kristiansand, Norway, where he developed in the musical environment since his adolescence.
