In 2020 Tomorrow's Rain entered the worldwide scene with the debut album "Hollow", the album summed up the band's previous years working in the underground scene, writing the songs for 4 years and played shows with acts as Paradise Lost, Kreator, Swallow The Sun and Tribulation as an opening act.

"Hollow" was a special debut, released both in English and Hebrew and featured many artists close to the band as guests during the songs, members of My Dying Bride, Moonspell, Rotting Christ, Septicflesh, Paradise Lost, Orphaned Land and Arch Enemy among others.

The album, released in the peak of the Pandemic made it impossible for the band to tour and in 2021 a special release show took place in Tel Aviv in the mid of the pandemic, My Dying Bride's vocalist Aaron Stainthrope was the band's special guest on stage, coming all the way from Yorkshire, the show was recorded professionally and later released as a live album "October Night In Tel Aviv" (A.O.P Rec).

Shortly after the band played few shows with acts as Tiamat, Rotting Christ and Samael and started to write "Ovdan" (the Hebrew word for "Loss").
