Most of the songs that were created during the Spiral wave sessions ended on the Spiral Drop demo album 'Ahead'.

Spiral Wave was the band formed in early 2000 by ex-Concrete band members: Zoran Basic (Vocals), Robert Trpin (guitars, vocals), Josko Putilli (guitars) and Ivica Djanovic (drums) after Marjan Desin (Beyond the Oblivion, F.E.B.R.A.) left the band. At the end of year 2000, Emir Mujdzic (ex-Puppy what's your name) joins the band on bass guitar. The band’s sound was influenced mostly by bands like Disturbed, From Zero, Tool, Incubus, Sevendust, 311, Helmet, Deftones, Snot, Nothingface, Slipknot, System of a down, Creed, Spineshank, Metallica, Faith no more, Rage against the machine, Foo fighters, Alice in chains, Soundgarden and many others.

In period 2003-2006 Spiral drop has changed the sound combining more electronic elements together with exploring some different progressive rock/metal areas. In 2008 second album 'Paragon' was released with 15 new songs. On the second album there were several guests participating on the new songs including and 3 cover songs. Vocals on song 'Empyrian' and on the cover song 'Time after time' (Cyndi Lauper) are recorded by Matej Trpin (ex-Nitrotaste, ex-Beyond the oblivion, ex-Klapa Kashe, OPG Band). Katarina Pavlicevic (ex-Klapa Fortuna) has landed her voice on 'Empyrian' and 'Pigeon song' (also cover of one traditional song called 'Golubice bila'). Anica Susic on vocals and Vedran Levi on bass guitar are guests covering Despina Vandi 'Gia'. Emir Mujdzic returned to band in late 2006 on bass guitar, and records track 'Time after time'.

In 2012 SDH Records has issued a re-mastered edition of the original demo named 'Ahead' with some new 'old' songs as a 10 years anniversary album with the completely new recorded sound.
