A new Marcel Loeffler album has been in the works for a while (with a release date set for this past spring...). Although there's still no info on its release date, there is now a webpage up for 'Around Gus', his hommage to Gus Viseur, including tunes written/played by Viseur, and originals.

As a side note, he designed the accordion on the album cover. Instead of bass buttons that play major, minor, and dominant 7 chords, he opted for major 7th, minor 7th, and alternating dominant 9th and 13th chords! :shock:
There are samples of him demonstrating it on his webpage with some nice solo work.
