The cool thing about Keith (besides the fact he likes Lindsey) is that he mixes country, rock and pop. He grew up listening to not just country, but John Mellencamp, Dire Straits, AC/DC, etc. so he has many various influences. It gives him a unique sound, IMO, along with the fact he's Australian, so his accent allows him to sing differently than your average American country singer.
Golden Road, Be Here and from what I've heard, the album out tomorrow are MUST haves. Hope you enjoy Keith!
