Trower gives us a hint in the opener "Whiskey Train" of what he  was later to offer us as a soloist. I think leader Gary Brooker's vocals in  this number influenced Trower as to what sort of voice he wanted singing  his material--that husky blues voice also made famous by David Clayton  Thomas and the late Terry Kath. As a result, the next voice we were to hear  a Trower number in was that of James Dewar. Also notable here is  "Whaling Stories", a lengthy (for its day) prequel to the classic  "Salty Dog"--plus, the sardonic, driving Elton John-ish  "Still There'll Be More". I think "Whiskey Train" is  one reason this album is rather undrrated and--at the moment--unavailable  in a US issue. It just doesn't sound like a Procol Harum song. What it  sounds like is a prelude to the the brilliant Hendrix-esque/ Claptonesque  blues-metal career Trower was to have.
