I need to elaborate on my pieces a little bit more..hmm..
Piece of Mind - Wilson - very innovative piece. Very odd with its 4 movements. Quite a fun piece to play.
Symphonic Metamorphosis - Hindemith - Well duh, awesome (when played well, or it may be a royal pain in the rear with the 2nd movement).
Carmina Burana - It just adds to the love of the song when you find out what the song is about!
Aegean Festival - Makris - very difficult piece technique wise. Very fast, very frolicky, and very very fun.
Techeli's work always caught my eye to an extent. Blue Shades and An American Elegy are awesome.
Redline Tango - another really difficult, fun piece to play. Played this at band camp this year at WTAMU. Lots of fun.
Liturgical Dances - played this my freshman year. Lots of fun.
Incantation and Dance - also played this my freshman year. Technical at points, but really fun none the less.
