This puzzle depicts tweets by @horse_ebooks, everyone's favorite spambot.

The way that two tweets are combined together is:

• Take the letters from each tweet
• Combine their values in ASCII with bitwise OR (which is pretty much the same as combining their binary values, but tells us which five characters to use after Z)
• Put back the non-alphabetic characters from the drawn tweet

The non-drawn tweet, in each case, is missing a letter or segment of letters, often repeatedly. These are the letters that are extracted.

Each of these tweets comes from a unique month, and when you rearrange these to the order given at the bottom of the puzzle, you get CALL IN S T R A VI N SKY. The answer is STRAVINSKY.
