From TT Instagram, a reunion of some sort of the original Stratovarius line up:
They started it all 34 years ago...The Dreamspace lineup of Stratovarius has reformed, returning under the moniker TIMO TOLKKI'S STRATO. Featuring Timo Tolkki (vocals & guitar), Tuomo Lassila (drums), and Antti Ikonen (keyboards), these members recorded the classic Fright Night, Twilight Time, Dreamspace and Fourth Dimension albums. Released in 1994, Dreamspace was the last Stratovarius album to have Timo Tolkki on lead vocals and includes such fan favorites as "Chasing Shadows", "Hold On To Your Dream", "We Are The Future" and "Wings Of Tomorrow". Tolkki recorded his vocals for the Fourth Dimension album demos before deciding to focus on guitar only and recruited Timo Kotipelto as vocalist. Fourth Dimensionincluded a number of standout tracks including "Against The Wind", "Distant Skies", "Galaxies" and "Twilight Symphony".
In the summer 2022 Timo Tolkki, Tuomo Lassila and Antti Ikonen met to discuss ideas to reform the original line up, deciding to call themselves “Timo Tolkki’s Strato”. In all secrecy, they have rehearsed in Tuomo’s garage (real back to the roots!) since January 2023.This reconstituted lineup has signed a deal with Warner Music Japan, and is currently recording their debut album titled Return To Dreamspace to be released on 27.10.2023, preceded by the single “(Is this the) Brave New World?". A Japanese Tour is planned for spring 2024, and Timo Tolkki will visit Japan in November 2023 to promote the album -- his first time there since 2007. Tours of Latin America and Europe are also in the works. In concert the band will be performing songs from Return To Dreamspace, as well as from the Stratovarius albums, Fright Night,Twilight Time, and Dreamspace.
