Outtake collections there are now many, of the most diverse bands. Some defects are characteristic of such plates, and "Coda" she has. There are songs that seem like sketches that sound just half done, like "We're Gonna Groove" and "Wearing And Tearing". On the other hand, there are plenty of "right" songs, again spray the the unique Led Zeppelin flair, something that never gave it back before and after this band. The best examples are "Poor Tom" and "Walter's Walk", a furious hard rock in the vein of "Sick Again". "Ozone Baby" is also heard, "Darlene" reminds me of "The Ocean" from "Houses ..." - album. Sometimes I have the impression that I would open with "coda" the notebook from Led Zeppelin. Some ideas are baked in, while others are more mature, incomparable rock'n'roll.
