Longtime Berkeley ska band the Uptones have a new guitarist. Emily Jayne is replacing singer/guitarist Musashi Lethridge, who has joined the English Beat. (They play the 142 Throckmorton Theatre in Mill Valley on April 23.) Jayne’s first show with the Uptones happens tonight at the Red Devil Lounge (benefit for Doctors Without Borders). Also joined by new permanent drummer Mike Stevens, the Uptones will play this year’s Warped Tour on June 26th at Shoreline Amphitheatre.
