When Jessica Pratt released her selftitled debut album, which she boasts had virtually no postproduction, the singersongwriter was critically praised for her austere guitar and hypnotic voice. The 2011 album’s imperfections were a feature rather than a drawback. It should come as no surprise then that the indie musician is proceeding with caution as she embraces a more complex and refined sound on her fourth album, "Here in the Pitch." Pratt spoke with AP entertainment reporter Krysta Fauria about the challenges of adding instrumentation, her process for coming up with an album and channeling 1960s pop music.
