Haim is a band of three sisters from the San Fernando Valley. They started in a cover band, Rockinhaim, that featured their parents. The sisters, from oldest to youngest: Este (she's the bass player, she's 6 feet tall, has Type 1 Diabetes, and has a degree in Ethnomusicology), Danielle (she's the lead guitarist, she's usually the lead singer, she drums on some of their songs, and I think she's also the main songwriter ... she has worked as guitarist and drummer with Julian Casablancas and Vampire Weekend), and Alana (guitar, keyboards, vocals). All of them are multi-instrumentalists.
