As a composer and improviser he utilizes musical instruments of his own design and construction, releasing many recordings on his own label Penumbra Music. During the 1980s he was an active member of Chicago's experimental and improvised music scene performing frequently with Gene Coleman, Michael Zerang, John Corbett, Terri Kapsalis, Lou Mallozzi, Jim Baker, Don Meckley and others. In the 1990s he performed at numerous music festivals in the United States and Canada including the Newfoundland Sound Symposium (in 1996 in duo with Johannes Bergmark), the No Music Festival (in 1998 with the Nihilist Spasm Band), and several others. Presently residing in southeastern Wisconsin he performs and records in a variety of projects with Steve Nelson-Raney, Chrisopher Burns, Matt Turner, Jason Wietlispach, Jim Schoenecker, Chris Rosenau, and Jon Mueller in various ensembles that have included Audiotrope, Raccoons, Scrawl, and PaVda releasing recordings with some of these ensembles on Crouton Records, Soutrane, Utech Records, and Necessary Arts. In 2007 he organized and led the quartet The LOST DATA Project (with Lou Mallozzi, Jim Schoenecker, and Jon Mueller) in performances at Woodland Pattern Book Center (Milwaukee), Elastic (Chicago), and the Sugar Maple (Milwaukee). In 2011 he founded the Great Lakes Improvising Orchestra to explore large ensemble open form and structured improvisation, an ensemble that includes many composers and improvisers active in Milwaukee's improvised music landscape. Presently, he improvises regularly with Christopher Burns in the duo Scrawl, with Linda Binder in the duo PaVda, and with Jason Weitlispach, Mark Mantel, Wilhelm Matthias, and Joshua Lesniak in the Oak Creek Ensemble.

In 2013, fourteen instruments designed and built by Hal Rammel were included in the permanent collection of the National Music Museum in Vermillion, SD. These acquisitions include many acoustic instruments built in the early 1990s that figured prominently in his work with Chicago improvisers and in his early recordings on Penumbra Music label. The National Music Museum also acquired four amplified palettes dating from 1997 to 2010.
