This album was released after LZ’s breakup. It consists of the studio album outtakes that weren’t used to fill the gaps on Physical Graffiti. Basically, its the eight worst tracks by the best rock band in the world. However, LZ (apparently) never wasted studio tape: all these tracks are worthwhile. I Can’t Quit You is a 1970 rehearsal of a blues cover found on the first album. Ozone Baby, Darlene, and Wearing and Tearing were three punk-influenced tracks recorded with In Through The Out Door. Bonzo’s Montreax is a drum solo in the spirit of Moby Dick. The others are tracks from 1970-2. Although the tracks are weaker than other Zep material, these songs are worth a listen from time to time. After the other 9 CD’s, buy this.
