Swampadelic has lots of rocking blues harmonica, New Orleans style piano by George Straits' pianist Floyd Domino. Drums by a woman who rocks, bass by a gentleman who has performed on 2 of Merle Haggards cds and who has performed with Willie Nelson. Banjo, mandolin, standup bass, harmonica, gospel and Memphis style back up vocals from a creole church group. Many have said that the vocals sound similar to Elvis on this CD. This is a very high energy, soulful CD that will make your feet tap.
