Major Problems, a seminal project by Lenny Dee and Ralphie Dee, figures among the Nu Groove's most influential releases. On that matter, Lenny D. declared: "I was in a very strange place, experiencing ecstasy for the first time. The UK government ran an advert with a guy attached to a life support machine with the slogan "The Effects Can Last Forever". This poster & billboard was all over the United Kingdom. Needless to say, I thought it was fuckin great, as I was totally into X".

Ralphie dee & Lenny Dee were producing, but Lenny's studio was not yet ready to mix tracks - so Frank Mendez from Nu Groove suggested a studio from a kid named Joey Beltram where he was signing some of his early freestyle tunes. Frank hooked them up & they (Lenny Dee & Ralphie Dee) made their first teckno tracks in Joey's studio. The tunes were made up of digital synths & drum samples from their drum machines. They used Lenny Dee's Rolland Juno Alpha 1 and the M1 Korg to name a couple, and also sampled their analogue bass line to give a loop type feel (which was after copied by other artists such as Puff Daddy).

The most well-known track of this EP, "Overdose (The Final Trip)", sampled 'Adonis - No Way Back's bass line, and was at the same time sampled by Ben Sims, Phil Vernol & Rob Jarvis' "Killa Bite 1 EP".
