Back in 2010, New York label Rong Music commissioned Rub N Tug to put together some edits as How & Why? for the first in a series of highly prized Promo Only 12"s. Over subsequent years, this series has seen contributions from Tiago, Prins Thomas, as well as plenty of names closely affiliated with Rong. Whilst the label may not be the most active these days, they have chosen to toast their 10 year anniversary with a 10th and final edition of the Promo Only series and have gone all out with a double pack of amazing edits by good friend and top vinyl aficionado Andi Hanley. The track titles alone should give you various degrees of clues as to the source material used by Hanley and it's a perfect way to end a series that has provided many selectors with long term secret weapons.
