The Flautissimo Flute Quartet was created online during isolation in 2020. The members are: Kremena Acheva, Gergana Ivanova, Petra Atanasova and Mila Tsankova. The first video they recorded during the isolation in the spring was well received, reaching 95,000 views online. This inspires the four ladies to present the best of the flute repertoire. In the summer of 2020, they performed in "Square 500" together with the vocal group Bella Voce, during the summer season of the Sofia Philharmonic "Romantic Summer in Square 500". Due to their great success, in November they made a solo debut concert in the Chamber Hall "Bulgaria", for which the composer Rumen Boyadzhiev-son wrote "Three miniatures for four flutes".
In the 2020/2021 season, the harpist Vessela Trichkova actively participated in their concerts. Rumen Boyadzhiev - son wrote "Prelude and Arabesque" for four flutes and harp. Inspired by their talent, American composer Catherine McMichael wrote the Sofia Suite for four flutes and a harp dedicated to the band, which will premiere in 2022.
