Wouldn't lacuna be trisyllabic? And can there be such a thing a "bisyllabic" (an unholy marriage of Greek and Latin)? The more common word would be "disyllabic" (not offending the Greek gods). More to the point, however, is that there might be more than just one hole; there perhaps are many smaller holes, best described by the plural term "lacunae". In any case, Tidal's jazz offerings are more than generous considering the price.
