"Pierre-Antoine Badaroux is a Paris-based alto saxophone player, composer and producer. He is working as a freelance composer since 2006, focusing on relations between sound, notation and the role of the musician in an ensemble. In 2008 he became an active member of record label and collective Umlaut Records, producing his own albums from the deconstructed Bebop of Peeping Tom to the original Composition No. 6, to a historical project on arrangers of Swing music with Umlaut Big Band that he leads, to the improvised music of r.mutt."

"For a number of years now, energetic double bassist, filmmaker and producer Grip has played an important role for the new scenes of improvised music in Europe. As founder of Umlaut Records, he opened up for creative forms of organizing collectives of musicians and promoting their music internationally. Since 2003 he has been one of the main organizers of Hagenfesten in Dala-Floda, Sweden, a stand-alone festival, and quite frankly possibly the most pleasant venue for free improvised music not only in Sweden but in the whole of Europe. Few other places offer quite the same endearing combination of sophisticated musical risk-taking, and up-beat, social get-together. GripÕs musicianship is informed by a similar knack for welding musical sophistication with social communication, often with an analog film camera at hand. With a handful of short films Joel Grip met mexican filmmaker Mauricio Hern‡ndez and shortly the film production company Umlicht was established. They are right now working on their third and forth feature film together. Umdicht is amplifying the pencil of Joel GripÕs hand, partly through the irregular issue of Lšsa Blad and partly in the future release of books."
