Back in the day when pop recording artists could still score hits with songs complaining about the music industry, Shawn Mullins, in the 1998 hit “Lullaby,” observed of Los Angeles, “It’s like Nashville with a tan.” But the troubadours and orchestrators inhabiting the L.A. drama “Lost Transmissions” are so inundated with and insulated by their life challenges that they’re as ashen as Siberian exiles.

Written and directed by (and based on some life experiences of) Katherine O’Brien, the movie, available on demand, stars Juno Temple as Hannah, a disaffected singer-songwriter lifted by the encouragement of Theo (Simon Pegg), a successful producer. Both characters take medication to treat illnesses, and early in the movie Theo expresses frustration: “I just think it’s a shame to live life with a filter over it.” Theo has schizophrenia, and once he stops taking his meds, what’s beneath the filter is a paranoid raver obsessed with a woman he calls “The Queen of Time.”
