90's

LOL. If you read my post it says "John Frusciante left in December."

The Chili's played in January, at a tribute to Neil Young. So if they have time for that they have time to jam in the studio.

A lot of the cores of their songs came from Anthony and John on their own. Anthony would come with some words and/or melody and John would craft some guitar around it, once they showed this to Chad and Flea the rest just played out.

I follow them to, man. I know when he left.
Playing a gig isn't the same as making songs in the studio. Plus 9/10 odds say the gig was booked last year some time and bailing means losing a lot of money so they show up and play regardless of any thing else.
A band in shambles is long for the circuit. If they get an album out I'll be surprised, if its any good I'll be amazed.
