JD Twitch secures a re-release of this rarity from Japanese label Nitelist Music in 2015, one which became a staple in his sets. The first of two 303 laudations is 'Infinity Sign', an unabashed piano epic, while 'Acid Air' is a forever-building percussive driver. No-nonsense acid but not quite as you know it, it's a timely tribute to the founder of Roland Ikutaro Kakehashi who died earlier this month.
