Immortal Soul is the fourteenth studio album by American heavy metal band Riot, released through Marquee/Avalon in Japan and Steamhammer Records in the rest of the world. It marked the short lived return of the Thundersteel touring line-up featuring vocalist Tony Moore, guitarists Mark Reale and Mike Flyntz, bassist Don Van Stavern, and drummer Bobby Jarzombek. It is the last Riot album to feature Moore, Jarzombek and long-time guitarist Mark Reale, who at the time was the only original member left in the band, before his death in January 2012.
