10x10 is a posthumous solo album by Ronnie Montrose. Ronnie had been touring with bassist Ricky Phillips and Eric Singer (Kiss) in the early 2000s. Over three days in 2003 at Doug Messenger's studio in North Hollywood, the sessions produced 10 strong tracks of rhythm guitar, bass and drums with the intention to get a singer to for the vocals. Eventually Ronnie decided on the 10x10 concept, 10 tracks and 10 different singers. Early on, he was able to secure contributions from close friends and collaborators like Sammy Hagar, Edgar Winter and Davey Pattison. In the intervening years Ronnie battled prostate cancer and, at one point, hadn't touched a guitar for 2 years. Conflicts in scheduling led to the record remaining unfinished for years up until Montrose's passing in 2012. Along with completion of the vocals, the songs also needed lead guitar as well. Rickey Phillips, with the blessing of Ronnie's wife Leighsa and assistance of Eric Singer, picked up the reigns and completed the album. "After he passed, I had to carry on with what Ronnie wanted, because he was such a purist. The songs were cut to 2-inch tape and then transferred to digital, but I really needed it to be a cohesive record. I've done enough records to know how easily the levels of 10 different singers can sound disjointed if you don't stay on top of the production." As per Singer, "I have to give a lot of credit to Ricky Phillips. Ricky really wanted to see this thing through. It was more for Ronnie than just for himself, or for ourselves. We really believed what we had originally captured had a certain vibe and a certain magic to the people in that room when it was created. We felt like, 'Hey, this thing needs to get done. We need to see this thing through, for every good reason.'"
