In 2004, Cobb joined up with Wildvine Music, a commercial music house in New York. During his time at Wildvine, Cobb played electric and acoustic guitar on countless television and radio commercials. Jim played alongside many renowned session players, such as Buddy Williams, Charley Drayton, Tony Tino, Will Lee, Babi Floyd, Ed Walsh, David Horowitz, Jack Cavari, Lou Marini, Jon Cobert, and many others. Jim’s contributions at Wildvine, however, weren’t just limited to one side of the glass. Cobb excels as an engineer as well as a player. At Wildvine, he tracked in various situations from simple voiceovers to rock, pop, & jazz ensembles, to full orchestras, and he's just as comfortable mixing these types of projects as he is tracking them. He also gained experience and fluency in the video world as well, producing show reels, editing video, and authoring DVDs.
