Mother's Milk is ze best!
As for OHM, I actually think it's a very good album notwithstanding Frusciante's absence... I love Navarro's guitarwork with its psychedelic twist (the end of Deep Kick is bliss). I don't think you can really argue with the first half of the album though I can see how the second half might require a bit of adjustment but it's worth it... Walkabout is as funky as any of their older stuff, Tearjerker is great if a little sappy, the S/T track has some nice buildups as well as that beautiful breakdown part after 3:45, and Transcending is fantastic!
Just flicking through the album is making me all nostalgic - this got a lot of play back in high school.
