Saw him in 1983 in Baton Rouge after Road Games was released. Great set. Allan was very laid back, not flashy and didn't even act like he was even the star, but we knew and loved hearing and watching the master play. R.I.P. Great Allan, you'll be missed. :(
I find it strange how he can write and play such great leads/solos, yet his rhythms are always overbearingly cheesy. Glad there'll always be Planet X, the lead guitar there is super similar and he even makes guest appearances with them.
I know this is a long shot since Allan truly is one of a kind, but I am looking for albums similar to the kind of complex yet accessible sound displayed on Allan's "Road Games" EP, and to some extent, "I.O.U." With or without vocals is really a non-issue, the most important thing is the overall feel of the whole thing. It's fairly easy to find artists (copycats or not) who sound somewhat similar to Allan when he goes all-out nuts with his alien fusion-style, but I have yet to find something that comes even remotely close to the ingenuity of tracks like "Water on the Brain Pt. II" or "The Things You See".
