The RTX New Music Challenge: Zack Walther vs. Brian Keane [AUDIO/POLL]

This week on The RTX New Music Challenge we've got the new one from Zack Walther Band, "If Love Was Enough" going up against the latest from Brian Keane, "Living is Killing Me."

First up, Zack Walther Band's "If Love Was Enough." Walther, who has brought new and captivating musical twists to the thriving Texas music scene with hits like "Down Easy", "Georgia Cane" and "So Hard" stays right in his wheelhouse with his new single.

This deep, hard hitting ballad, which can be found on their 2011 "Into the Fray" is vintage ZWB -- give it a listen.

Next up, Brian Keane. Although he's a name you might not recognize, yet, Keane's all ready leaving his mark on Texas and Americana Music. Keane was a founding member of the Band of Heathens, he wrote "She Left Me for Jesus" with Hayes Carll (the 2009 Americana song of the year) and played keys for the Randy Rogers Band.

With songs like his latest and "I'll Sing About Mine", which he took Top 5 on both Texas charts and is covered on Josh Abbott's new album "Small Town Family Dreams", Brian is making a name for himself as a blue-collar, man's man singer.

His latest tribute to hard working "Living is Killing Me" is our challenger this week. Take a listen.
