Four extended compositions from the Tubass Quintet led by Szilard Mezei (performing on double bass instead of his usual viola) performing with a heavy group of 4 double bassists and tuba. An unusual configuration playing unusually named tracks (HEP 15, HEP 16, HEP 17 B, HEP 58/2), but clearly playing a unique rendering of jazz, swinging music from the lower end of the spectrum, with an open and accessible nature.
