No...All Zepplins songs sound the same. They're like Godsmack, but from the 70's.
Explosive, iron-clad proof that you don't know what you're talking about.
That was one of the gripes of the idiotic music press back in the day, that they never delivered the same sound.
In fact, to say that their songs all sound the same is simply preposterous as they, like the Beatles, and Queen, are one of the few bands that can play anything
"Hot Dog" is honky-tonk electric country
"The Rain Song" actually sounds just like elevator Muzak until the guitars kick in big at the end.
"Carouselambra" is techno -Disco
"The Crunge" is James Brown Funk with mellow synth added in.
"Darlene" is like Avant Southern Rock
The overplayed "D'yer Mak'r" is reggae-tinged
From pounding cave man 4/4 beats to crazy-ass time signatures that musical wizards have to study to get right.
They had mountain-shearing straight forward, Blues-oriented Power Rock, like a thinking man's Black Sabbath, and delicate acoustic instrumentals.
They did Proto-Punk, New Wave, mild, cheezy crooning stuff like "I'm Gonna Crawl".
They did Folk, Folk-Rock, elaborate guitar orchestral compositions...Boogie Woogie, Rock-a-Billy, plain old Blues, and even noise/experimental music as well as all of the Moroccan-influenced stuff.
Their influences were as disparate as Elvis, the Damned, Bert Jansch, Wagner, Joni Mitchel, Joan Baez, B.B. King, The Rolling Stones and the Who, classicla music, ethnic musics, ancient Celtic stuff and Glen Miller.
Mandolins, theremins, hurdy gurdys, moog synthesizers, steel drum sounds in electronically modified drums, kettle drums, violin bows, pedal steel guitar, mellotrons, violin bows, standard tunings, open tunings, invented tunings
Say whatever you want about 'em, but as for "all their songs sound alike", that's like saying 2+2=13. It can only mean that you're not familiar with their albums.
"Rock and Roll" sounds nothing, NOTHING like Kashmir sounds nothing like "Dancin' Days" sounds nothing like "Southbound Suarez" sounds nothing like "Since I've Been Loving You" sounds nothing like "Bron-Yr-Aur" sounds ABsolutely nothing like "Communication Breakdown".
Absurd.
