Around the same time, after moving from the Bay Area to the city by the lake, Chicago, he founded his own label, Barely Audible records. His first release on Barely Audible was IE (For Large Ensemble), easily his most well-received and well-known record to date. The composition demonstrated the potential of the budding reedist as a writer and performer. Created for a 27-piece ensemble, the album includes long, patience-testing (yet ultimately rewarding) numbers as well as quick, rambunctious ones.
Rosenberg hasn't composed anything up to this level since, but he's been plenty busy with other projects. In 2000, he recorded a schizophrenic, 99-track LP with Shiurba, called One Liners, and a duet with Anthony Braxton, called Compositions/Innovations 2000. He also found time to open his own small club in Chicago, where he performs along with a host of aspiring musicians on a regular basis. His most recent project is an experimental quartet entitled Rosenberg Skrontet. V: Solo Improvisations was issued in early 2001.
