It is not known whether or not time sign is intended as a "concept" album, however there is a very even flow one composition to the next in a near seamless progression of tunes. Also, all the tunes are very even in their production, creativity and artistry and it is difficult to pick out particular standouts from the others on the CD. One tune that does bear some individual attention is the second cut on the CD, "Ballad for 12" an Ove Johansson composition. In this work, the group demonstrates their high level of artistry in collective improvisation. The quartet ebbs and flows with the "spotlight" shifting focus on one member then another while the other three fade into a more accompanying role. Another tune that "tickles" the ear is the last one on the recording, Ove Johansson’s "Twelve Times." What drew this listener’s attention was an effective shifting of the sound from one channel to another in the early stages of the piece before bringing it all together very effective especially if one is listening on headphones.
The average jazz listener should not be put off that Susanna Lindeborg’s Mwendo Dawa is avant-garde jazz. It is true the sounds created by this Swedish quartet go well beyond traditional conceptions of melody and harmony, however this is a very accessible recording. For those listeners who enjoy avant-garde sounds, time sign certainly will be full of welcome sounds. The recording would be an excellent addition to any jazz aficionado’s CD collection.
