You can't go wrong with any of the Chili Peppers' first five albums, but I've always been of the opinion that Mother's Milk is the best of them. It just sounds like a band at their peak, in several ways. It's relentlessly energetic, there's a consistent focus on funky jams, and it's the ultimate party metal album.
Everyone talks about the fantastic cover of Stevie Wonder's classic Higher Ground, but that causes it to overshadow the rest of the album. Opener Good Time Boys is probably my favorite, a funky hair metal classic. Subway to Venus takes the old school P-funk vibe of their Freaky Styley album and combines it with the big sound of this album. Nobody Weird Like Me and Punk Rock Classic straight up thrash, and the former perfectly contrasts the explosive and galloping riffs and drums with some touching vocal melodies. The swaggering Sexy Mexican Maid is a particular fantastic song as well.
Just like it opens with a bang, it closes with the massive funk stomp of Johnny, Kick a Hole in the Sky. After a bassline that sounds right out of Among the Living, it's all slapping hooks and catchy Funkadelic-esque chant choruses.
Mother's Milk is one of funk metal's finest, especially on the glam metal influenced side of it, nothing beats this, Extreme, and Mindfunk's debut for total funky party metal.
