The MonaLisa Twins, with real-life twins Mona and Lisa Wagner fronting the band, are one of the very few modern groups who continue the tradition of song-writing that took off in 1963. They bring back what has been started 50 years ago and write modern songs in the 60s Beat music tradition, reviving the genre with a fresh twist without sounding pop-ish or trivial. Their signature features are their tight twin harmonies and unaltered natural voices.
