Boone and Foster are a contemporary bluegrass duo whose recording work has appeared on Mountain Fever Records, one of the more active independent bluegrass labels of the present era. Mountain Fever, based in the American South, has released recordings by a range of traditional and progressive bluegrass acts, and Boone and Foster's work has been part of that catalog.

In 2022, the duo released "I've Never Been So Lonesome" on Mountain Fever, adding to a body of work rooted in the close-harmony vocal tradition that has been central to bluegrass since the music's earliest years. The single reflects the label's commitment to presenting contemporary bluegrass artists who work within the genre's established vocal and instrumental conventions while bringing their own voices to the material. Boone and Foster's recording joins a substantial Mountain Fever catalog that has helped sustain the independent bluegrass recording ecosystem through the label's consistent output.
