Ronnie Montrose had been playing music for over 40 years, and believe it or not, this is the one and only live DVD recording of his career.

Ronnie and his band created a very wonderful evening filmed at the Uptown Theater in Napa, California this past January 27th, 2012. This DVD includes acoustic pieces, songs you never heard him perform before, and ones you haven't heard him do for years and years and years.

Ronnie rocked the house with a great set list that included many of his big hit songs including: 'Rock the Nation', 'I Got The Fire', 'Make It Last', '20 Flight', 'I Don't Want It', 'Space Age Sacrifice', 'Rock Candy', 'Bad Motor Scooter' and 'Good Rockin' Tonight'.

Live At The Uptown will begin shipping on May 1st and is available as a regular DVD, DVD with limited poster and DVD with limited edition poster (no metallic). The limited edition, numbered poster is 12.5" x 19", black Speckletone paper, with three-color - "a very special and historic item!"
