This is Led Zeppelin's best CD. No other CD truly defines this band better than their self-titled debut. All songs on this album are indispensible. Dazed and Confused is a masterpiece, as is Babe, I'm Gonna Leave you. But the real heart and soul of this record are its blues tracks You Shook Me and I Can't Quit You Baby anchor the album. Zep was always at their best playing the blues, just check out Since I've Been Lovin' You. Your Time is Gonna Come still gives me goosebumps, and How Many More Times is the hidden gem on the album. Zeppelin would never top the overall consistency of this album, it is a true landmark in rock history and should be in every fans' collection.
