The members of Oko Tygra shared their hypnotic, '80s-influenced dream pop in our studio four years ago. Since then the Denver quartet -- led by singer and guitarist Joshua Novak -- has remained relatively quiet, playing intermittent local shows and working on new music. The band is back in the local spotlight this month with the release of its debut album, "Assistoma." Oko Tygra recently returned to the CPR Performance Studio. The band members played three songs and spoke with Jeremy Petersen about why they don't play as many concerts as some bands, the years of work that went into "Assistoma" and the themes of solitude and isolation behind the new music.
