No doubt Big & Rich have mellowed since the goofball rallying cry of “Save a Horse (Ride a Cowboy),” embracing a steadier, more sentimental sound. Following 2014’s ballad-heavy Gravity, Did It for the Party is a bittersweet, reflective album, where even the rockers (“Congratulations (You’re a Rockstar),” “Funk in the Country”) seem to exist in the rearview, tempered by wisdom and age. “Let me tell you, son, number one/Number one was having fun,” they sing on the title track—a lyric couched not just in the past tense, but sung to a younger future generation.
