Singer-songwriter Dominique A has given stellar material to a string of gifted, enigmatic performers. He’s penned hazy, floating alt-pop for Françoiz Breut, gripping urban tales for pop veteran Jane Birkin and sombre acoustic ballads for late rock luminary Alain Bashung. He also crafted the string-powered “Bagatelle”, a striking collaboration with composer/multi-instrumentalist Yann Tiersen.
