Adrenaline recording sessions started (when?) in 1994

[chi_no]

I noticed that the 'Tones have started performing songs like Nose Bleed (Nosebleed), One Weak, Minus Blindfold, Lifter, Fireal, Fist, Birthmark and Oraled (Bored)
[– other than the old/pre-Adrenaline ones (Seven Words, Roots, Engine Number Nine)]
in early 1994. With what I'm assuming that they've started recording the album (Adrenaline) in the way early 1994.
But I only know that these songs were first played March (1994).
[Of cource the process involved the re-recording of the pred-Adrenaline songs]

... But what I really want to know is - Does anybody know a comfirmed date/moth in which the Deftones started working on the album?

Proof:
The Berkeley Squere show(s) in San Francisco, CA, USA from April 29/30th, 1994.
