Brandi Carlile and The Twins playing the Perelman Theater in October

Singer songwriter Brandi Carlile is going out on a tour in October, and it’s got an interesting twist. Brandi and The Twins (brothers Tim and Phil Hanseroth) will play various venues completely unplugged with no amps or microphones.

For the Philly show, Brandi will be playing the Perelman Theater on Saturday, October 4th. Tickets go on sale this Friday, August 15th here. While there’s no news about any new music on the way, Brandi has published Caroline, a children’s book based on the lyrics of her song “Caroline,” which was featured on her 2009 album Give Up The Ghost. Brandi recently became a new parent and welcomed a daughter, Evangeline Ruth, into the world this past June.

Tickets to Brandi Carlile’s “Pin Drop” tour go on sale this Friday here.
