10x10 is a posthumous solo album by Ronnie Montrose. Ronnie had been touring with bassist Ricky Phillips and Eric Singer 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 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. Ricky Phillips, with the blessing of Ronnie's wife Leighsa and assistance of Eric Singer, picked up the reins 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.
