Like Swimming is Morphine's best CD (I haven't heard The Night yet, though). It's hard to write about it since Mark Sandman's death, but I will try.
Like Swimming builds off the strengths of their previous album, Yes. Their unique sound created by a saxophone, two-string slide bass guitar, and drums is both suppressed at times by Sandman's halting vocals, and at others unleashed with amazing force and beauty. Take, for example, the difference between the hauntingly sublime "I Know You (Pt. 3)" and the chaotic "11 O'Clock". Only Morphine could deliver these two opposite styles of music with such perfection.
One of the best things about Morphine is that they cannot be pigeon-holed into a genre or a style of music. Are they rock, or jazz, or alternative, or what? You also cannot say, like so many other bands, they are "a cross between 'so-and so' and 'someone else'" because no one has ever played music like this. Have you ever heard of a two-string slide bass guitar? Or a Double-Saxophone? All this is just a part of the genius of Mark Sandman and Morphine.
I think PJ Harvey once said that Morphine is one of the sexiest bands ever. I agree with Harvey. Morphine's low, smoky sound is perfect mood music for, well, you know.
