Though the Preservation Hall Jazz Band has been performing and recording since 1963, That's It! is their first album of entirely original material. Although it may seem counterintuitive for an ensemble devoted to maintaining the original spirit of New Orleans jazz to present all-new songs, co-producers Jim James (My Morning Jacket) and Ben Jaffe suffuse these tracks with an authentically vintage aesthetic that's enriched with the city's rich musical heritage. The style is raw and soulful, from the trumpet-blaring fanfare of the title track to the growling gospel of "Dear Lord (Give Me the Strength)." Still, despite all the brassy bombast, the album's most sublime moment comes with the haunting piano solo "Emmalena's Lullaby."
