The description I received was that they wanted a chess piece as the symbol, and the text to say either the full band name or just the letters HL. I chose a knight as the piece to use because it's arguably the most illustrative of all the chess pieces and is asymmetrical, which makes it more of a symbol and less of a badge.
Whilst it followed their instructions it ended up looking very corporate and clearly wasn't suitable for a band at all, especially given that they really like The Ramones logo and wanted to use it as an influence, something they told me afterwards.
