Preston Brust and Chris Lucas go by the name LoCash, but they raised plenty of money for the kids at St. Jude at a recent fundraiser.

The concert has become a tradition for the duo, who raise money for St. Jude Children's Research Hospital every December. The benefit brought in $8,000 in its first year, and more than $30,000 in its fourth year, which was this holiday season.

LoCash partnered with a local country station in Herrin, Ill. for the acoustic set, which also featured songwriter Phil Barton. In addition to the revenue from ticket sales, an auction boasted Brust's vest, Lucas' shoes and an autographed basketball and game-worn shoes from some Indiana Pacers players. Barton's handwritten lyrics to Lee Brice's hit song 'A Woman Like You' also brought in $800.

The concert sold out in just five days in 2014, and the duo are already looking forward to next year, discussing the possibility of adding multiple shows.

“We are so proud to have started such a meaningful tradition with Z100 in Illinois to help kids and families of St. Jude,” Brust tells Country Weekly. “Each year it just keeps getting better, and every year we raise and reach our goals. The sky is the limit with this thing. It’s exciting to imagine how much money we can all raise for St. Jude in the future.”

“It’s my favorite show of the year,” Lucas adds. “I hope it just gets bigger and bigger and bigger because we can’t do enough for the kids at St. Jude.”

LoCash are planning to release a new single after the turn of the year, their first under the auspices of a new deal with Reviver Records.
