They also started to record their own music from the very first song, and shortly after the forming of the group they joined a professional recording studio and made their first cassette. This was the most common media for amateur bands at the time, because almost nobody had a CD player in those days. They even had their own concert in the same period, gathering about 200 local young rock lovers. This was sensational for an amateur band of this age, playing their own music. But this success continued to follow the young rockers, and soon they was the favorite rock band in the hole region, the county of Norway named Telemark.
This cassette was very soon sold out, and the band went back to studio for another recording. This time the cassette was given the name "One step Closer", which was exactly what happened. The local newspapers wrote about the band almost every week, and wherever the youth was gathered, Intruder was there to play their own popular material in concerts with loud guitar, smoke and pyrotechnical fireworks. The public loved them, and the cassettes was once again sold out. Their music was also daily heard on radio stations, both local and national. Then late in 1987 Intruder was signed by a small record company named Hill Records, and started recording in January 1988, A 12" vinyl single with 3 songs was released, and Intruder was once again in the center of attention in that part of Norway. They also released another cassette, this time with the very creative name: "Volume 3". The band was now in a steam of productivity and did also appear on a local 7" vinyl single together with another local band.
All the attention in local press and national radio, gave them the opportunity to play support for famous Norwegian musicians as: Stephen Ackles, Åge Aleksandersen, Stage Dolls and many others. They also was first choice in every local arrangements including musicians, and this also gave them support gigs for international super stars as: Little Steven and Dr. Hook. There was also an opening for a support job, playing on the Iron Maiden tour, but the financial terms was completely unrealistic for an upcoming amateur band from Norway at that time. However the band was, by this time, well known in the right circles, and was also recorded live on "TV Norge" from the stage "Bootleg" in Oslo on two different occasions. This two concerts was sent several times in full length on this national TV station.
The fourth cassette, and the very last recording made by Intruder, was named "Changes". In this period the band faced some internal social problems and disagreements, and the fact that a Danish record company wanted closer contact as well as winning the "county championship in rock", was not enough to keep the band together. Two of the members wanted to play jazz, and the world missed the new recordings they made. "Changes" was never released or sent to any contacts, radio stations or friends in the business. Unfortunately, in 1990 the fun was over, and the rest is memories. A lot of good memories tough, but still just memories. ~ Phillip Ewing, 80s Retro Music
