Brand New Man by Brooks & Dunn: Released August 1991, The debut studio album from the legendary duo of Kix Brooks and Ronnie Dunn, launching a career filled with chart-dominating honky-tonk and neo-traditional anthems.
This album had songs on their greatest hits album which was the 1st or 2nd country album I bought when I started listening to country music. It's a greatest hits, so it's cheating, but still one of the best albums of all times imo:
Everything was great in 1991. One helluva football season too.
