Room 335 was Larry's signature song from his first solo album, and the name of his home studio where he's recorded pretty much all his solo work.
He did a lot of the studio charts for Steely Dan sessions, as well as playing on a lot of songs - Kid Charlemagne, Don't Take Me Alive, everything but the solo on Josie and I think Peg, too. He admitted in a Guitar Player interview after his first album came out that the opening chord progression for Room 335 was pretty much a direct lift from Peg (the last chord of the sequence is a little different.) He's also the soloist on Donald Fagan's solo album, The Nightfly.
Larry has been one of my favorite players for forever. I've seen him a couple of times and he's always astounding. He was supposed to do a concert here in Denver with Robben Ford late last year, but it got canceled and rescheduled for a day I had to be out of town. My buddy went to the show on my ticket and had them BOTH sign a CD for me.:thwap:
