Lost Not Forgotten Archives: Quarantième – Live à Paris is an official live release in Dream Theater's archive series. The recording captures the concert the band played in Paris in February 2020 during the Distance Over Time tour, shortly before touring worldwide came to a halt. The set spans the whole career, with 'Metropolis Pt. 1', 'Hollow Years', the complete 'Octavarium' and 'Pull Me Under', performed by LaBrie, Petrucci, Myung, Rudess and Mangini. The title – French for 'fortieth' – refers to the band's fortieth anniversary, for which this recording appeared in 2025.

This edition is a 4-LP on black vinyl.
