The goals for what would eventually become the Motherlode Canyon Band were to have fun and play acoustic music.
During the past two decades, a handful of musicians have performed with the band, and the sound has morphed into blues and rock.
Still, throughout that span, Williams and Hall have remained true to what they are - musicians who will play anywhere they can.
To celebrate their 20th anniversary playing music together, the Motherlode Canyon Band will perform at the Egyptian Theatre on Saturday, Oct. 26.
The concert will feature the current lineup — Williams,
"We've had several bass players, drummers and singers, and my thoughts, now, turn to those people and all they added that helped this thing come this far, but working everyone who has been a part of the band into the set proved to be a task that was undoable for us," he said. "However, we did invite all the past members to the show and some will show up."
Hall said the reason he and Williams are lucky to have played together all these years is timing and connections with the community.
"We started right when the boom began in Park City and we were tied to the real estate community, the different nonprofits and developed through the gigs we were afforded through them," he said. "As the town grew, there were more opportunities for us to grow."
Williams said he appreciated the community, but also acknowledged the support the musicians have received from their families, including Hall's late wife Lois, who passed away last year.
"They understand that we're all a little whacked and, even though Dan and I are in our late 50s, we still get home at 3 o'clock in the morning sometimes after a show," Williams said. "It's taken a special group to support us.
"Lois was very flexible about so many things that allowed us to go out and play so much," he said.
Throughout the past 10 years, Williams and Hall have felt the support of their current band members' families as well.
"Our singer Nina, who has been with us for 10 years now, has seen many changes," Williams said. "Her kids have grown up and her youngest is on the verge of graduating high school, and her husband has been a great supporter."
With all that support, Williams and Hall have been able to play in Park City as much as they want without having to break into the Salt Lake market.
"What's most exciting now is that we do a varied amount of music, and I think that's what keeps it fun," Williams said.
The diversity stems from the guitarists' musical influences.
Hall is an Eagles, Crosby Stills & Nash kind of guy who learned to play guitar with Jimi Hendrix and Cream albums.
Williams cited Doc Watson, the Grateful Dead and the rds as some of the artists that caught his ear.
"Also, all the musicians that have come and gone and come and stayed have led us to the direction we are at now," he said. "I think right now, we're the tightest we've ever been and have the widest range of musical background in the musicians."
Looking back, both Hall and Williams said it's been "mostly fun" playing with each other.
"The players aren't only great players, but all great friends," Hall said. "And it's a tight unit, emotionally too."
"The fun thing was that Dan and I liked different things and had different influences, so we're sometimes at each other like an old married couple, but that was something that kept us going all these years," Williams said. "Dan is a prolific songwriter and, to me, one of the greatest things is seeing people mouthing the words to the songs as we play."
