According to his obituary, Blackstock was remembered for pursuing the “cowboy way of life he always wanted to live.”

“In his early adult years, Brandon moved to Nashville and began his career in the music business,” the obit stated. “He played important roles in shaping the careers of many larger-than-life celebrities and left a lasting impact on everyone who met him. He always had his hand out to pull others up the ladder, to open a door, to make a connection. Many industry insiders have Brandon Blackstock to thank for their opportunities.”

Following more than two decades in the music business, “Brandon found his way back to the mountains and the cowboy way of life he always wanted to live. He found a homestead and a love in Butte, Montana.”

“Brandon didn’t do anything halfway,” the announcement stated. “He charged into life with both guns blazing. He was a cowboy … and valued the cowboy way of life. He drove a big truck, rode a good horse, and removed his hat when he introduced himself. He was a sharpshooter, a man’s man, and a true gentleman. He loved a hard day’s work that started early and finished late.”

The notice continued, “He had no schedule for when it was time for a cold Coors Light, and his Wrangler jeans were no stranger to a Copenhagen can ring. He rode bulls, but he did not take any. There were no elk, deer, or fish who weren’t slightly afraid of him. He was honest and earnest. He was loyal, hardworking, and loved hard.

“But never did his star shine brighter than in his role as a father. Nothing mattered to Brandon more than his four beautiful children, Savannah, Seth, River, and Remy. To say he was devoted seems cliché. It feels like an overused word, but it is the correct word. He was a devoted father. His four children were and will always be his greatest love and his greatest legacy.”
