Bob Ludwig, a Portland-based engineer who has tweaked the music of everyone from Bruce Springsteen to Beyoncé, has a chance to win a Grammy Award for the fifth straight year.

Ludwig garnered two Grammy nominations Monday. One is in the category of Album of the Year for “Sound & Color” by the rock band Alabama Shakes. The other is in the category of Best Engineered Album, Non-Classical, for the same album.

The Grammy Awards will be held Feb. 15, 2016, in Los Angeles and will be aired on CBS.

On both nominations Ludwig is named as mastering engineer. Ludwig’s work, mastering, is the final fine-tuning done to a recording. Most of the time, Ludwig works alone in his Portland studio, though some musicians have been known to drop in on him.

There are only five categories in which mastering engineers can win Grammy Awards. Last year Ludwig won three, including Album of the Year for “Morning Phase” by Beck.

Ludwig said Monday that he and Adam Ayan, both of Gateway Mastering in Portland, looked through the nominations list Monday and saw 16 other nominations for recordings they mastered, including work Ayan did for Carrie Underwood and Tim McGraw.
