Unless the choice is between a blowjob or Chris Robinson and Co. Then Chris and Co are the thing I need second most.
When I was 19, just after my girlfriend died, my buddy came over with a guitar and handed me mine. We taught ourselves (he taught me) She Talks To Angels. For about two hours we played it badly, through tears and missed chord changes. It was better than therapy.
When my dad bought me my second guitar (Uncle Charlie bought me my first) he told me, you say what you can't say with words with that thing. And when you feel like you have no one else to talk to, you tell your guitar.
I am a shitty guitar player and an only slightly better bass player.
But sometimes I will pick up my guitar and not notice what my fingers are doing. I will hear a thing and realize, wow, that sounds cool. Then I will realize I feel better (even if I didn't know I was down before).
Buy your kid that musical instrument.
