I always thought some of The Who's stuff was very Zeppelin like, especially on their "Who's Next" album, which is great آپ should definately check it out. ACDC have that hard rock sound which came straight from Zeppelin. Highway to Hell & Back in Black are their two standout albums. Jeff Buckley is very much like the quieter sound of LZ. Many people have کہا that his voice is very similar to Robert Plant's and his songwriting style is very ... deep xD
آپ could تلاش around on some Classic Rock radio stations - a lot of classic rock is influenced سے طرف کی Zeppelin. Hope this helped!
There was a band in the early-mid 70's called 'Sir Lord Baltimore', and some of their material was mistaken as being Led Zeppelin when it first got airplay. I haven't listened to the LP in ages, but I remember that my پسندیدہ song on it was called 'Kingdom Come'. I guess I'll have to dig through my album collection and give it a listen sometime soon. Perhaps آپ might be able to find something سے طرف کی them on youtube.
