About Us

Having already established themselves in their respective markets of the Pacific Northwest and the Midwest, Mike Thrasher Presents and Mammoth, Inc. officially joined forces in November 2021 uniting the Portland, OR and Lawrence, KS based companies. The companies aligned under one umbrella with a combined 41 years of experience. The transition came after the devastating loss of industry veteran Mike Thrasher at the age of 48 in March of 2020. Per request of Thrasher’s family, the Mike Thrasher Presents name transitioned to Mammoth NW and Mammoth, Inc. is honored to continue Thrasher’s legacy.

Originally founded in 1994, Mike Thrasher Presents was founded by local musician Thrasher, who is one of the principal promoters in the Portland, OR area. Thrasher oversaw the company’s growth which includes a 2009 partnership in the Hawthorne Theater; the company now books 500+ shows a year across the Pacific Northwest. The company has expanded well beyond the indie, metal, and punk beginnings promoting shows of all music genres including Warped Tour, Flogging Molly, Slayer, and G-Eazy, as well as burlesque acts such as the Suicide Girls and Dita Von Teese, comedy acts such as Duncan Trussell and the Trailer Park Boys, and even art shows such as Pancakes and Booze.

Mammoth launched in 2006 and produces a wide range of events including concerts and full-scale festivals, along with tour booking. Venues include amphitheaters, arenas, small independent clubs, numerous boutique theaters, and 50+ historic indoor theaters as well as an independently owned venue portfolio. The company is co-owned by Jeff Fortier and Josh Hunt who together have over 55 years of combined music industry experience. Based out of Lawrence, KS and Kansas City, MO Mammoth produces 1,000+ concerts and live events across the country per year.

Mammoth is proud to partner with the Mike Thrasher organization, continuing to bring great music to the Pacific Northwest under a new name. Visit our homepage for upcoming shows and events. The broad range of genres in our calendar guarantees something for everyone. We hope to see you at a show soon!
