Mestre Bergman presents this week Pinegrove. From the collision between the traditions of indie and folk with Americana roots comes Pinegrove, a quartet from New Jersey captained by singer and composer Evan Stephens Hall. They define their music as “music for the promotion of introspective partying”, a statement that helps to intuit the precious, melancholic songs and the mixture of electric guitars, banjo and pedal steel guitar. A delightful breath of fresh air for the rock in which there is a good dose of the roots of Wilco and the indie candor of Built To Spill. On Thursday at Primavera Sound.
