The clearest comfort blooming in the darkness, a dreamlike Christmas night presented by Nell! The moving moments from the brand concert of South Korea's representative emotional rock band, Nell (NELL), 'CHRISTMAS IN NELL’S ROOM 2019', are revived as a record. This concert, held at Jamsil Students' Gymnasium in Seoul from December 21 to 24, 2019, celebrated the release of their 8th full-length album [COLORS IN BLACK] and showcased deeper and more intense musical colors than ever before. The intricate and spectacular laser and lighting production, a symbol of Nell's concerts, blended with the songs from the 8th album such as 'See You in Five Minutes' and 'When I Become Helpless', instantly immersing the audience. Signature songs like 'Time Walking on Memory' were reinterpreted with Nell's Room's unique warm sensibility. This live recording, released on December 23, 2020, is a record of the diverse emotions (Colors) found in the darkest places (Black), and it perfectly captures the comfort named Nell that visits us every winter.
