Not his best, but essential because it was Zappa's first album to really encompass 'all' his styles and set the pattern for many differnt songs to appear over the next 25 years. Many songs included here appear in better versions elsewhere, but I keep coming back to the oridginals. Very imaginative. Not a 5th star because I never go through the 37 minute film excerpt that is included. Also Tengo na minchia tanta is too much out of place here. These tricks he should reserve for his live albums, most notably the YCDTOSA series
