BITOI is a Swedish-Danish quartet made up of Cassius Lambert on electric bass and vocalists Alexandra Shabo, Lise Kroner, and Anja Tietze Lahrmann. The group’s name is an acronym for “bass is the only instrument,” which, although technically true of the group, is somewhat of a misnomer: upon hearing Shabo, Kroner, and Lahrmann, one could easily say that they have attained mastery of their instrument of choice: the voice. This choir of three form the throughline of BITOI’s sound, guiding and leading Lambert’s bass through songs that are equally humble and lavish. Through his processed electric bass – which utilises pitch-shifting and an array of other ghostly effects – Lambert spins gorgeous spectral melodies that belie the bass guitar’s reputation as predominantly a low-frequency instrument. Between the voices and the bass guitar, there is an uncanny sense of interspecies communication; this comes into clearer focus once you learn that the band’s lyrics are based on phonetic pronunciations of bird sounds. This otherworldly, more-than-human element brings a rapturous liveliness and unpredictability to BITOI’s electronic folk music.
