Oakland-based band T Sisters, made up by siblings Erika, Rachel, and Chloe Tietjen, made a stop at Acoustic Guitar magazine’s studio for an interview and an intimate performance as part of the magazine’s Acoustic Guitar Sessions.

The band’s influences include Indigo Girls and the Andrews Sisters, and in Acoustic Guitar’s words, “They deliver the kind of seamlessly intertwined harmonies that only a family can muster.”
