But I have no idea who he is.
Well, now I know he's Anthony Kiedis from the band Red Hot Chili Peppers, but I never heard of him or the band, until on the Simpsons episode "Krusty Gets Kancelled" (May 13, 1993). And hardly at all since.
They apparently haven't made much of a splash in traditional pop venues, but they've torn up the alternative rock charts, with lots of albums and singles reaching #1, including "Give It Away," "Soul to Squeeze," "Scar Tissue," and "Californication."
So that's where they got the name of that tv series starring David Duchovny.
I listened to these songs, to determine if I've ever heard them before. Nope.
Some of the lyrics seem relatively heterosexist:
"Scar Tissue" is about feeling the breasts of a young Kentucky girl.
"Californication" is about a pregnant teenage girl whom the singer wants to marry.
Some aren't:
"Give It Away." I don't know what he's giving away, but he's giving it to his mother, father, and brother, so I imagine it's not sex.
"Soul to Squeeze": he's in love, but doesn't specify with a man or woman.

He's straight, not to be confused with fellow insect-named performer Ant, who is gay.
Both performers are pro-gay, supporters of gay marriage, and open to speculation about their own sexual identities.
There have been 12 other members of the Red Hot Chili Peppers over the years, but these four are the "classic group." From left to right: Chad Smith, Anthony Kiedis, Flea, and probably John Frusciante.
