The St. Louis rock quartet scored a number one hit with 'Champagne' in 2009. Now Cavo returns with the untitled follow-up to their major label debut -- 'Bright Nights, Dark Days'. You can hear and download the new song 'Thick as Thieves' here.

Cavo hope to avoid the sophomore slump with their second major label record, which is still untitled but has a tentative spring 2012 release date. They have released their new track 'Thick as Thieves' and are allowing fans to download it for free for a limited time only.
