In “Rooms Filled with Light,” Fanfarlo presents an entirely different sound than in their first album, “Reservoir.” The first track, “Replicate,” contains many of the same prevalent strings as some of the tracks from “Reservoir,” but the song teeters with vocals that break out from that routine. For another band, this could result in a song that spends the whole time building towards an explosion, but burns out before it gets there. Instead, Fanfarlo uses it as a launching point for the album. Listeners cling to Simon Balthazar’s voice as he leads them into the next song, “Destruction,” which begins with the same synthetic start as some of the songs from “Reservoir.” It then busts into some surf rock mixed with ’80s style pop. Needless to say, “Destruction” resonates as the catchiest song on the album.
