Q: Question: What age was the producer on Tobias' artist compilation album? Passage:Prior to the launching of her next output, Tobias was cast on the screen in Krute radosti (2002) and Zostane to medzi nami (2003), respectively. Musically, she first returned on various artist compilation Tak to chodi (2003), produced by Michal Horacek. Following that, her second BMG album was issued on December 8, 2003. As with her previous release, neither Punto Fijo achieved a presence in the official albums charts. Nevertheless, its ballad repertoire with jazz, folk and ska-inspired music brought Tobias favorable feedback from music critics. In 2006, she appeared as guest on Horacek's follow-up project, Strazce plamene. The multi-platinum compilation and Andel Awards-nominee for the Album of the Year, included a solo track designed for herself by Petr Hapka "Na hotelu v Olomouci". The composition wouldn't crack the Radio Top 100 Oficialni, but her vocal performance has been generally viewed by many as the best of the set, and singer gradually started to gain her own fan base in the Czech Republic.
