On his 1999 LP Eletro Ben Dodô, Lucas Santtana updated Seventies tropicalia rock, sampling Caetano Veloso behind what appears to be reimagined Tom Zé album art. Sem Nostalgia also goes back to the future, using just acoustic guitar and voice to make an utterly modern LP. On "Cira, Regina e Nana," digital technology turns a whop on a guitar into the sound of an electric typewriter; on "Super Violão Mashup," plucked strings conjure something resembling an Afrika Bambaataa electro-funk jam. Like Feist and Tune-Yards, Santtana erases the line between acoustic and electronic music, waxing nostalgic without the nostalgia.
