Berceuse by Robert Beaser (b. 1954) played by Adam Eccleston, flute & Zaira Meneses, guitar. This comes via the Boston Guitarfest 2014, Jordan Hall, New England Conservatory. Produced by Brian Dixon with audio captured by NEC Audio/Visual. The Boston Guitarfest have been releasing some fantastic material via their YouTube Channel. Pretty piece by Beaser. FYI, a Berceuse is usually referred to as a lullaby or something around that mood. I like the writing, spacious and melodic but some nice harmonic language.
