Doc meets pretentious performance artist Siobahn, who clashes with Jace and the others. Doc dates Siobahn and irritates the band by bringing her to rehearsals, dressing more stylishly and redecorating his house. The band members finally revolt when Doc tries to make them integrate a sitar into their sound and allow Siobahn to sing. Doc is mad that Jace was allowed to bring in Sarah yet Siobahn is rejected. Jace fights with both Doc and Siobahn. Lucas becomes exasperated with the conflicts and quits, leaving the band without a drummer again.

After their outstanding performance at the Boulevard Boys concert Jace goes on an ego trip wanting to perform at bigger venues and refusing to play certain jobs, frustrating the band. Jace decides that the band should go on a much needed break but soon feels betrayed when he visits a club and is surprised to see Sarah and the rest of the band playing jazz songs such as ""Stormy Weather"" onstage without him. They don't understand Jace's feelings of betrayal, which he discusses with his mother Gina who he thinks is also being betrayed when he spots his father with another woman. Although the mood is tense at SlipDog's next show, the band plays better than ever before, even playing a rock version of ""Stormy Weather,"" but only after Jace makes a shocking announcement. Soon Jace gets a shock of his own when he meets a representative from a major record label.
