There are separate styles of music attorneys in the music business.  Some are into just hanging out and pretending as if they're in the band itself while others are more conservative and stick to the business side.  There are power broker/agent types, who are good negotiators but not particularly good attorneys, and excellent attorneys who lose sight of the big picture.  Then there's everything in between so chose carefully.

Lawyers can serve as agents or managers while simultaneously practicing law. In the music industry, lawyers procure recording contracts for their clients and help manage their career by participating in career strategy and deal making. Unlike agents, lawyers usually do not regularly book personal appearances for their clients. Thus, lawyers often tend to act more like managers than agents. Personal management requires daily and detailed attention to the personal affairs and logistics of an artist. Because an experienced music lawyer may know the business better than an inexperienced manager, the attorney who has a proactive relationship with the artist and manager may find himself or herself making recommendations, facilitating relationships, creating opportunities, and advising the manager as well as the artist. By doing so, the lawyer becomes, in effect, part of the management team. In some cases, the attorney may be invited by both artist and management to take on duties which are generally the prerogative of artist management. This usually means representation on a contingent fee basis and greater involvement with the artist's daily affairs in addition to providing general legal counsel. By limiting the work a lawyer can dedicate to other legal clients, the attorney may become more like a company general counsel or "in-house" lawyer.
