"Also, there's an energy with my band and I, because we haven't played 'Bluebird,' really, since it's been 'Bluebird.' So we're really happy to be up there and playing music." The two-time Grammy winner said her song "came at a really crazy time," and that, in terms of its message, "we obviously would never have known what we were writing when we were writing it." "But when it became a single, it was kind of the beginning of 2020," Lambert added. "So I think it was kind of a little beacon of a song of hope for people. It was for us, so I'm really thankful that it came out when it did, and that it helped people through something."

Earlier this month, she, Jack Ingram and Jon Randall debuted the first single from the trio's upcoming album, The Marfa Tapes, which will be released on May 7. The track, "In His Arms," was presented alongside its accompanying music video, which features the songwriters performing in Marfa, Texas, with a stunning backdrop of the desert sunset. The album's 15 songs were written and recorded over a five-day period last fall in Marfa — the desolate town Lambert, Ingram, 50, and Randall, 52, call a "songwriting haven," where they laid down stripped-down verses outdoors with just a pair of microphones and an acoustic guitar as background noises of a crackling fire and sounds of the desert can be heard. The Grammy Awards, hosted by Trevor Noah, will air Sunday at 8 p.m. ET/5 p.m. PT on CBS Television Network and Paramount+.
