The Haters changed their name after only three days to Ebba Grön, which originates from a police code in connection with the so-called Operation Leo, where the German terrorist Norbert Kröcher planned to kidnap the Swedish Minister for Immigration Anna-Greta Leijon.

When Ebba Grön went in hiatus in 1981 due to bassist Lennart "Fjodor" Eriksson having to serve time in jail for refusing military service, the three remaining members (Thåström, drummer Gunnar "Gurra" Ljungstedt and keyboardist Anders "Stry Terrarie" Sjöblom) formed side-project Rymdimperiet (Galactic Empire).

With a then-modern sound firmly set in the 80s and a more focused leftist political stance combined with easily accessible songs, Imperiet became one of the biggest Swedish bands of the 1980s.

In an attempt to cross over to international audiences, Imperiet also recorded an album with some of their songs translated to English.

In 1992, he started the heavy industrial rock band Peace Love & Pitbulls, with lyrics in English.

The Swedish audience longed for a new rock album so when Thåström in 1999 released the album Det är ni som e dom konstiga, det är jag som e normal (You're the Strange Ones, I am the One Who's Normal) it became a very big success.

A large portion of the proceeds from the merchandise sold on this tour was donated to the cause of the homeless people in Sweden.
