Michael Sunday produced a late-night show on KPFA in Berkeley. Since 1982, he has hosted folk and blues radio shows, first on station KERG, in Redway, California, and then briefly on KHSU at Humboldt State University in Arcata, and, since shortly after it went on-air, KMUD, in Garberville. His show is streamed on kmud.org Saturday mornings 10:00–12:00 am, Pacific time. At 25 songs per show, he estimated he had played over 47,000 tunes as of late 2020. During the 1970s, Denson spent several summers as a volunteer river guide with Bill McGinnis's Whitewater Voyages, primarily working with inflatable kayaks. He was a guide on the South Fork of the American and Klamath rivers usually, and on one Klamath trip met Mary Alice Sexton, who later became his third wife. In the summer of 1980 they ran the Grand Canyon on a month-long private trip with Bill McGinnis and two other guides. He and Mary Alice moved to Humboldt County in 1980 and for 15 years operated Kicking Mule records from the barn on their ranch. After dividing the masters with his partner, Stefan Grossman, in 1995, he sold the remaining masters and the label to Fantasy Records.

He was president of the Civil Liberties Monitoring Project (CLMP) for many years, and became a nonviolence preparer for the Citizens Observation Group (COG). In that capacity he travelled extensively in southern Humboldt County, training over 200 people in nonviolent techniques to use while monitoring police activity during marijuana raids. In 1990 after extensive litigation by CLMP, the government signed a consent decree to alter their raiding techniques, thanks in large part to the advocacy of Ron Sinoway and Mel Pearlston. In 1992, Denson ran for Humboldt County supervisor, but came in fourth in a field of eight. In 1995, he enrolled in William Howard Taft University's Taft Law School, a distance learning institution, from which he graduated in January 1999. He passed the California Bar Exam that month and in August 1999 was sworn in as an attorney. His practice for the first 16 years had been focused on defense of people charged with marijuana crimes or driving under the influence of alcohol or drugs. He has also represented,
