Rideau!, Un Drame Musical Instantane's second LP, shows the trio advancing from the sonic experiments of their first effort, Trop d'Adrenaline Nuit, for an album that is less skronky and far more lyrical and flowing, without sacrificing the avant-garde elements. On this record Un Drame Musical Instantane trades in the AMM-styled noisescapes of the first record for something more in the realm of Fred Frith and/or Tom Cora, music that is melodic but still beyond the borders of categorization. Bernard Vitet's trumpet and flugelhorn add a stronger jazz element to the proceedings, and like the earlier album, everything on this disc was improvised spontaneously. Each musician takes up between two to five instruments on most of the tracks, so that Un Drame Musical Instantane sounds more like a larger group than a trio. Like most Un Drame Musical Instantane records, there are plenty of quirky touches, like a menacing voice counting off numbers on "M'Enfin" or the strange electronic blips in the middle of "La Critique."
