Best Coast is an American rock duo formed in Los Angeles, California in 2009, currently on hiatus. The band consisted of songwriter, guitarist and vocalist Bethany Cosentino and guitarist and multi-instrumentalist Bobb Bruno. Cosentino, a former child actress, began writing music as a teenager and was formerly a member of the experimentalist drone group Pocahaunted. After a brief stint at college in New York City, Cosentino returned to the West Coast and began recording lo-fi demos with Bruno, whom she met in the Los Angeles music scene.

Yellow Bird Project is a company that collaborates with indie bands to raise money for charity, primarily through the sale of T-shirts. They approach indie bands, asking them to choose a charity and submit an original design. Each design is then printed onto T-shirts and sold exclusively through the YBP website to raise money for the charity of the artist's choosing. Some of the bands which they have collaborated with include Andrew Bird, Bloc Party, Bon Iver, Broken Social Scene, Devendra Banhart, and The National. Over the years, the company has diversified to include book publishing, album releases and film projects. In 2016, UK based charity Trekstock took over the management of the project, enabling all funds to be raised for one cause - young adults living with cancer.
