In 1996 Leo recorded some demotapes (C-Cassette) and sent them to Tresor Records in Berlin. Some selected tracks were released in 1998 as "6AM" EP and the record got quickly a lots of attention and was placed in many DJ-charts, starting Leo's recording career. The second release "Tontunmäki" EP (1999) was also a success and became one of Tresor's most ordered back-catalogue titles.
