There's really not much you can say about an LP that has zero recording information -- no credits, not even a recording date.
It appears that there were two releases under the Mountain Dew Brass moniker -- Instrumental Hits of Country Girls and Johnny's Cash and Charley's Pride. The ensemble name comes from the bargain basement label on which they were released -- Mountain Dew Records. The company was based not in Nashville but in Newark, N.J. Their products were sold in discount stores and truck stops.
The two LPs were issued with consecutive catalog numbers, probably somewhere around 1975. Both albums were issued with similar cover photos and exactly the same black-and-white sketch on the back.
The Mountain Dew Brass was an obvious attempt to cash in on the success of Danny Davis and the Nashville Brass. Still, the music is listenable instrumental pop and the sound quality is quite good for cheap vinyl.
The content of Instrumental Hits of Country Girls was pretty obvious -- brass versions of songs made famous by top female country singers. Among them was Loretta Lynn's To Make a Man.
To Make a Man
None of the Mountain Dew Brass material has made it to a digital format. However, the LPs are frequent visitors to the thrift store bins.
