Jeroen Tel — "S-Express"
Group
Nostalgia — founded February 1995

This 2004 crack intro from Nostalgia features a SID tune by Jeroen Tel — one of the most celebrated composers in C64 history — titled "S-Express" and preserved in the High Voltage SID Collection. Graphics were provided by Cupid, a handle that also appears in Avantgarde intros of the same era, and Nostalgia — abbreviated N0 — was founded in February 1995 with an active web presence at n0stalgia.org. The group is one of the most prolific in this collection, with entries including #256 NO 02, #983 NO 03, and #206 NO 08 among several others. Doc Snyder's page documents an extensive intro sequence with coders 6R6, Jedi, Erhan, S!R, and Didi rotating through releases, and scrolltexts consistently closing with their motto: "Come to where the legend lives."
