The head of the household sets the standards, makes the rules, and can break them as they see fit. Priya Carlberg, vocalist, composer, and maestro leads Birthday Ass wherever she directs, and on Head of the Household, she announces her unique musical vision in boisterous fashion. Carlberg formed Birthday Ass with her friends from the New England Conservatory. Their backgrounds in jazz and improvisation evokes a certain idea of artistry: strictly serious, cold, and academic. The ensemble at once meets and defies those expectations on their sophomore album, Head of the Household. Carlberg composes every part of these invigorating songs, each instrumental line and each lyric, and creates unexpected and multifaceted rock songs. The method and mastery behind Birthday Ass are as astute (pun intended) as can be, but the music that results overflows with an infectious, unfiltered vitality.
