What do you get when two of your top 10 favorite bands go on tour and start a YouTube video battle covering each other’s songs? Well, besides a happy Krissie, you get a challenge to help a much needed cause.

After Alpha Rev covered Carbon Leaf’s “Let Your Troubles Roll By,” Carbon Leaf decided to strike back and post a video of them covering Alpha Rev’s “Black Sky.” (video below)

If you’ve been living in the dark, Texas had a severe drought this summer and the excessively dry conditions sparked raging wildfires around the state.  Alpha Rev lent their song “Black Sky” to a couple of causes promoting wildfire relief funds.

And here’s where Carbon Leaf ups the cool factor: They are giving away their cover of the song for free and encouraging fans to make donations to one of two Texas wildfire relief funds if they download the song.

That’s seriously amazing.  So I downloaded the song and donated $5 to the Texas Wildfire Relief Fund (you can also give to Pass the Hat for Texas) I don’t live in Texas.  But, some of my best friends and best bands do and I love the city of Austin like it’s my home.  Not only that, but if North Carolina were to go up in flames, I’d like to think that others around the country would support the firefighters here as they battled to save land, people and property. I challenge all of my friends, fellow music junkies, Carbon Leaf or Alpha Rev fans to make a donation to one of these causes.  A) Because its the right thing to do and B) Because these artists are insanely cool for using their time and talents to bring attention to the cause.

Then go support these incredible artists on tour.
