Radiation 2013 (5.1) is a complete re-recording and remix of Marillion’s 1998 studio album Radiation, presented in high-resolution DTS-HD Master Audio 5.1 surround. Originally mixed under tight deadlines, the band revisited the album 15 years later with a fresh perspective—remixing, re-recording, and in some cases reinterpreting the material to match their original vision. The result is a richer, more dynamic listening experience that highlights the emotional depth and sonic detail of the songs. This 5.1 edition is a must-have for audiophiles and fans of immersive progressive rock.
