Rob Thomas' first solo album in six years, The Great Unknown boasts a little something for every modern pop fan. Lead single "Trust You," co-written by OneRepublic's Ryan Tedder, is an infectiously propulsive blend of acoustic guitar strum and banging kicks imported from club music. Even more dance-oriented is the funky, sexy "I Think We'd Feel Good Together"; it gives Adam Levine a run for his money in the blue-eyed soul department. For those longtime fans yearning for the passion and moodiness of the singer's early years with Matchbox Twenty, both the title track and "Pieces" are must-hears.
