Frank Callari, who managed the Mavericks, Ryan Adams, Junior Brown and Lucinda Williams, among others, died of natural causes Oct. 26. He was 55.

After graduating from the Hotel Ecolier in Lausanne, Switzerland, with a B.A. in hotel/restaurant management in 1973, Callari became the general manager at a New York hotel. In 1976, his desire to get involved in the music industry led him to attend New York University, where he graduated with a B.S. in music technology.

While attending NYU, Callari became the program director of its radio station, WNYU, which led him to be a self-employed club DJ and dance record re-mixer in New York.

Callari moved to Miami in 1988, where he eventually met and began managing the Mavericks. The band was signed to MCA Records, and he and the band moved to Nashville in 1992.

Callari and then Mercury Nashville label chief, now Universal Music Group chairman, Luke Lewis launched the Nashville-based Lost Highway Records in 2001, which is home to Williams, Adams, Shelby Lynne and Mary Gauthier, among others. For the first few years of the label's existence, Callari was senior VP of A&R.
