UpStream Enterprises is the LLC that was formed in 2017, the year Nadine started to produce SnowyGrass. The festival was so successful and fun that Nadine wanted to do more with music events. In 2018, she decided to produce a concert at the Historic Park Theatre--one concert to try it out and see if she could succeed. In the planning stages, she realized that the energy and resources needed for one show didn't really increase too much with planning 6 shows. She did 9 starting in January 2018! The first show featured Meadow Mountain and Ran Off the Rooster. This followed with ONDA, featuring Bridgett Law (Tierro Band and founding member of Elephant Revival) and Silas Herman. More shows included: The Alcapones and Banshee Tree, Man About a Horse, Cary Morin and Matthew Wilburn Skinner, Goodnight Texas, Gypsy Jazz Fest with La Pompe, Aaron Walker, and Harmonious Wail. The Honey Dewdrops traveled in from the East Coast and were joined by Bonnie and Taylor Sims, and KC Groves. The series finished out with a bang with Ray Wylie Hubbard and Jon Pickett. Then on to the 2nd SnowyGrass! 

In the fall of 2018, after another successful festival, she started getting antsy to do more. On the 2nd weekend of February 2019, she hosted a Mountain Songwriting Retreat at Murphy's Resort in Estes Park. The one songwriter she knew she wanted to work with was Clay Rose of Gasoline Lollipops. The other main songwriting coach was Esme Patterson, formerly of Paper Bird and who has cowritten and performed with Shakey Graves. Arthur Lee Land (Great American Taxi) and Carol Lee also coached. Kicking off the retreat at a welcome reception was Johnny Miller of Lonesome Days. Clay and Esme performed an intimate Listening Show that the public could attend. ​In August 2019, UpStream Concerts produced a listening show with Jeff Scroggins and The Scroggdogs.

The Songwriting Retreat was repeated in February of 2020, with Clay returning as a coach. Charlie Rose (formerly of Elephant Revival) performed for our students at a reception dinner at Nicky's Steakhouse. We were excited to have Neyla Pekarek (formerly of The Lumineers) join us as a coach, as well as Daniel Rodriguez, founding member of Elephant Revival. The listening show performed by these artists was memorable.

Incredibly, in August of 2020, SnowyGrass was held as a distanced, limited capacity event. It was successful in being able to pay working musicians and sound engineers who had lost so much work due to COVID 19. It also was a healing, live music experience that people seemed to need. The Songwriting Retreat did not happen in 2021 or February of 2022, but it will happen again when things are safer. Meanwhile, more SnowyGrass!
