For the last three years, former Talking Heads frontman David Byrne and Annie Clark , aka St. Vincent , have been writing songs together.  Now, the duo has announced that they'll be releasing their collaborative album in September and have planned a two-month North American tour to support it.    

Titled Love This Giant , the new album will feature 12 new songs with vocal duties shared evenly between Byrne and Clark.  “This material would get passed back and forth -- each of us adding and elaborating on it,” said Byrne in a statement.  “We both had other records and tours in the works, so this project was done in fits and starts, and each series of recording sessions involved a lot of players.”

Byrne added that he considers Love This Giant to be “a pop record.”  “I started to sense that we were ending up with a sound and approach I’d never heard before,” explains Byrne.  “There were elements that were reminiscent of things I’d heard, but a lot of it was completely new.”

Just a few days after the album is released, the duo will hit the road to perform the album as well as “a bunch of songs that we suspect people will know.”  The trek kicks off on September 15 at the State Theater in Minneapolis and will make stops in New York, Nashville, Dallas and Los Angeles, among other cities.
