Karen: This week the latest Led Zeppelin remaster came out: Physical Graffiti, almost 40 years since the original release. These have been uneven releases -some of the bonus material has included out-takes that sound barely different from the songs we know so well. In this case, the bonus disc has a few surprises; still not the live performances one might have craved (only the Led Zeppelin first album remaster has had that so far), but these rough versions of familiar songs are worth a listen. "Sick Again" is only instrumental, with no vocal track, and the opening sounds a bit different. The version of "Houses of the Holy" proves the old adage of less is more, as it is burdened with both a clunky cowbell part and weird backing vocals. An early version of "Into the Light," titled "Everybody Makes it Through," sounds almost like a different song, with what might be a harpsichord playing a prominent role. But beyond the bonus material, this is a great album, one of their best, and it sounds wonderful. With songs like "Kashmir," "Ten Years Gone," and "Boogie with Stu," it's an example of Zep's versatility and talent.
