Only 3 releases I own, but they are a big 3:
- Pink Floyd - Dark Side Of The Moon. Perhaps the most iconic rock album ever. 741 weeks on the album charts. Ranked #43 on Rolling Stones list of best albums. I remember my listeneing to "Money" in Moddle School music class, the teacher talking about using everyday sounds as part of music composition.
- Doobie Brothers - The Captain and Me. Though not as "important" as DSOTM, this was the first in a long string of Top 10 album for the Doobies. A solid album, with the Classic Rock classics "China Grove" and "Long Train Runnin'".
- Led Zeppelin - Houses Of The Holy. Probably the 5th most popular of Led Zep's 8 studio albums, Houses Of The Holy still topped the Billboard album charts, and sold 11x Platinum. It ranks #149 on the Rolling Stone list (#148 on the 2012 update) behind I, IV, Physical Graffiti and II, all of which are Top 100.
