Early on the label specialized in artists from around Tennessee, then branched out to musicians and singers from throughout the USA. They offered a vairety of country music, rhythm & blues, gospel music, rockabilly, pop music, and early rock & roll.
After the move to Hollywood, Dot bought up many recordings by small local independent labels and issued them nationally.
In 1958 Dot started a subsidiary label, Hamilton Records, for rockabilly and rhythm & blues.
The label produced many albums by hiring artists with hit records in previous years to record remakes of their earier hits.
