Bloomington-based singer-songwriter Cody Diekhoff, known as Chicago Farmer, was in Colorado Springs promoting a new album when the pandemic hit. He and his band, the Fieldnotes, packed up and went home. Diekhoff said he wasn't terribly eager to make another record after that. Six years later, Homeaid is here, dropping March 6 on vinyl, CD and streaming platforms. The band returns to the Castle Theater to promote the album on March 28.
