There have been a few great Aussie Blues Bands over the years and it sounds to me like you may have the makings of another one. Great tune ,vocals and groove.At first i thought the 'spacey' 'verbed harp didn't quite fit ,but after a couple of listens i really liked it. Adds (literally) another dimension to a Blues boogie. Might just be my sound system but to my ears the Harp could be a tad louder when it comes in? Got any more stuff you could put up?
