I totally agree. It's a masterpiece. The backing track sounds really heavy, even today. Double drums, guitars, basses, keys. It's brilliant. The harmonies and modulations are out of this world. Love both Jan & Dean's vocals on this one. Great backups by The Matadors (and Jan, Dean,) and Brian Wilson??) It all culminates in one of the most exciting rock songs ever produced. Jan was advancing so quickly in 1963 it's insane. Everyone in Jan's team was so talented- Dean, Roger, Don, Brian, Lou, Wrecking Crew, etc --- but Jan was a genius. Those records were totally visionary and ahead of their time
