In-between periods in Roxette and Gyllene Tider reunions, Gessle recorded numerous solo albums, both in Swedish and English. After Fredriksson's illness in 2002 he released "Mazarin" (2003). The album was a critical and commercial success for Gessle and started the beginning of a long term collaboration with the backing vocalist Helena Josefsson. With Fredriksson's continued treatment and recuperation he made three more albums, "Son of a Plumber" (2005), "En händig man" ("A handy man", 2007) and "Party Crasher" (2008). After Roxette's Neverending World Tour finished in 2015 he produced another set of solo efforts, "En vacker natt" (2017), "En vacker dag" (2017) and "Small Town Talk" (2018). In 2016 he started using the pseudonym Mono Mind, first releasing a few singles before delivering a full album, "Mind Control", in 2019. Gessle was the main songwriter for both Roxette and Gyllene Tider.
