A little remember "First Aid Kit" to "The Pierces" and their wonderful album "You & I". And a further comparison suggests itself: Just what concerns the singing, I must, insbesonder stop thinking about the two singers of the fantastic ABBA "This old routine". No one has the song so unique celebrated duet as Agneta and Anni-Frid. By Klara and Johanna arrived there, it will take a bit longer. But they have what it takes and are still young enough. They should create!
Anspieltips: "This old routine", "Emmylou", "Blue", or just listen to the whole album!
