Michael David Rosenberg, better known by his stage name Passenger, is an English singer-songwriter and musician. Previously the main vocalist and songwriter of Passenger, Rosenberg opted to keep the band's name for his solo work after the band dissolved in 2009.

Passenger’s upcoming album Whispers II will be released via his own label, Black Crow Records, on April 20, 2015 and 100% of all profits raised will go towards Unicef UK’s groundbreaking initiative in Liberia. Every year ten thousand children die of malnutrition in Liberia. Over the next five years, Unicef UK aims to reach every child under the age of five in the country, and protect them from the danger of malnutrition. Mike Rosenberg (aka Passenger): “It's so exciting to be able to work with Unicef on such an important campaign. Money raised from these sales will go directly towards food and supplements to help bring severely malnourished kids back to health, facility upgrades and maintenance, education and training for health workers in the region."
