After falling in love with Hendrix, being turned on to British styled blues by Jethro Tull, this was the album which woke me up to how powerful rock music can be! There's only a few times when an album, on first hearing, absolutely fires your being and you have to hear it constantly - maybe just to re-assure yourself that this is real rock music, or maybe just to be sent on a sonic roller coaster ride. My two favourites tracks are "Communication Breakdown" due to Page's guitar work, and played loud, still makes the hair on my neck stand, and their major work, "Dazed and Confused", so much more feel to it than "Stairway" and more akin to "Kashmir" for it's depth,darkness and power, but still stands as one of the finest showstoppers ever!!
I heard LedZep2 before hearing LZ1, and still think it's a more powerful statement of intent.
I still think most bands' first to third albums are often their best, even though they are considered less polished, or lack production values of their later offerings, but, Led Zep 1 is, for me their mightiest, rawest, and ultimately, the most satisfying of all the Led Zep collection, considering most of their albums are the best there's been. An awsome debut from an awsome band!!!! Start at the beginning then get the lot!
