Hailed as one of the 50 best ambient albums of all time by Pitchfork, Vernal Equinox was the first commercially released work by Jon Hassell, originally put out by Lovely Music in 1977. It is also the debut of a pioneering new form of music that would become known as "fourth world": a subtle blend of field recordings, electric jazz, ambience and global music influences. Hassell's trademark FX-soaked trumpet is carefully embellished by a studio ensemble including the master Brazilian percussionist Naná Vasconcelos and David Rosenboom on synth. The result is a quiet, meditative and highly original work of outstanding beauty.
