Deep Purple "Machine Head"
Purple was as close to Zeppelin as anyone ever came. They were recording at the same time as Zep, so they are both from the same genre. Deep Purple “Burn” is also an excellent album (albeit, recorded by a different version of the more popular Machine Head era “Mk 2 lineup”).
Ritchie Blackmore is every bit as exciting a guitar player as Jimmy Page. Check out Deep Purple.
