With three new and valuable members joining the band, Patrícia Relvas and Roberto Afonso brought together Diogo Sousa, Pedro Branco, and Ricardo Dias Gomes to join their Lavoisier project. This is an impressive sonic and musical expansion, as normal, but it also follows an indomitable desire for Portuguese words, spoken and sung, to travel to more territories. era com h is precisely the record of these two journeys, of music and poetry, with an invitation extended to a dozen contemporary writers from the four corners of the Portuguese-speaking world.
