RdL is a Japanese duo, was formed in 1999 by Mondii (who runs labels SPEKK, PLOP, Lantern) and Naph (working as sound engineer). They are playing instrumental music which I would consider in a similar vein as Six Parts Seven, Dif Juz, Eisi, Penguin Cafe Orchestra or early records by Tristeza or Collections of Colonies of Bees.
