Debuting at #1, From the Cradle by Eric Clapton is 100% blues. This album was released on the heels of "Tears in Heaven" which likely contributed to the popularity of this album. According to this fan ranking site it's one of his best albums. While other people may find it great, it doesn't make a big impression on me. For me, Slowhand and Unplugged are much more interesting. Certainly, From the Cradle is well done, but it just doesn't make me feel the things some of his other work does.
My recommendation is to check it out, you may like it, or not.
