On 
Qualquer, 
Arnaldo Antunes drifts even further away from the rock and pop sound that made him famous as the frontman of 
Titãs during the 1980s. 
Qualquer has a calm, simple, and down-to-earth sound that soothingly floats along in the boundaries between bossa nova and singer/songwriter-styled folk music. No percussion is used on the album, as 
Antunes is backed by the musical quintet of Cezar Mendes and Chico Salem (both on acoustic guitar), Edgard Scandurra (electric guitar), Dadi Carvalho (bass), and Daniel Jobim (piano). The opening track, "Para Lá," written by 
Antunes together with 
Adriana Calcanhotto, sets the tone of the album and is also one of its highlights. There are also collaborations with 
Carlinhos Brown (on "Lua Vermelha" and "Sem Você") and 
Marisa Monte (on "O Que Você Quer Saber de Verdade" and "Contato Imediato"). For the first time 
Antunes also presents versions of "Não Sou da Sua Rua" and "As Coisas," two of his own compositions that were recorded in the early '90s by 
Marisa Monte and 
Gilberto Gil, respectively. "Acabou Chorare" is an elegant cover of an old song by 
Morães Moreira and Galvão. 
Antunes singing is very low-voiced, almost timid sounding, and his characteristically unorthodox and humming voice lends the music an unstudied and ingenuous air. ~ Philip Jandovský
